Merge branch 'master' into feat/service-host

Deleted BaseModel and BaseService classes, along with their
associated using statements and members. This removes the
abstraction layers for database, logging, and state management
from EnvelopeGenerator.ServiceHost.Jobs.

-# EnvelopeGenerator — AI Context Reference
-
-## Purpose
-Digital document signing system with **unified Blazor WASM frontend** for both Senders and Receivers. Senders create envelopes and place signature fields. Receivers view PDFs, sign documents, export stamped PDFs.
-
-**Primary Libraries:** DevExpress + PDF.js (PSPDFKit removed)
-
----
-
-## Deployment Architecture
-
-**Two Presentation Projects (Both Required):**
-
-1. **EnvelopeGenerator.API** (ASP.NET Core Web API)
-   - Runs independently (development & production)
-   - **YARP Reverse Proxy** configured via `yarp.json`
-   - Proxies requests to:
-     - `EnvelopeGenerator.ReceiverUI` (Blazor WASM)
-     - External Auth.API service
-   - Serves as single entry point for all requests
-
-2. **EnvelopeGenerator.ReceiverUI** (Blazor WebAssembly)
-   - Runs on separate host/port
-   - Accessed **only through API proxy** (not directly)
-   - Serves static files (HTML, JS, CSS, WASM)
-
-**Request Flow:**
-```
-Client ? API:8088 (YARP Proxy) ? ReceiverUI:52936 (Blazor WASM)
-                                ? Auth.API:9090 (External Auth Service)
-```
-
-**Configuration:** `EnvelopeGenerator.API/yarp.json`
-

-## ReceiverUI Route Structure
-
-### Root Route
-| Route | File | Purpose |
-|---|---|---|
-| `/` | `Index.razor` | Application entry point (landing page). |
-
-### Sender Routes
-| Route | File | Purpose |
-|---|---|---|
-| `/sender/login` | `LoginSenderPage.razor` | Username/password authentication |
-| `/sender` | `EnvelopeSenderPage.razor` | Sender dashboard (envelope list) |
-
-### Receiver Routes
-| Route | File | Purpose |
-|---|---|---|
-| `/envelope/login/{EnvelopeKey}` | `LoginReceiverPage.razor` | Access code authentication for specific envelope |
-| `/envelope/{EnvelopeKey}` | `EnvelopeReceiverPage.razor` | View & sign envelope (PDF.js viewer) |
-
-**Multi-Envelope Support:** Receivers can login to multiple envelopes simultaneously (per-envelope cookie authentication).
-
----
-
-## Architecture Evolution
-
-### Old Architecture (Deprecated)
-- **Sender UI:** `EnvelopeGenerator.Web` (Razor Pages + PSPDFKit)
-- **Receiver UI:** `EnvelopeGenerator.ReceiverUI` (Blazor WASM + PDF.js)
-- **Backend:** `EnvelopeGenerator.API`
-
-### Current Architecture
-- **Unified Frontend:** `EnvelopeGenerator.ReceiverUI` (Blazor WASM) — **Both Senders & Receivers**
-- **Backend:** `EnvelopeGenerator.API` — **Both Senders & Receivers**
-- **Libraries:** DevExpress + PDF.js
-- **PSPDFKit:** **REMOVED**
-
----
-
-## Solution Structure
-
-| Project | Target | Purpose |
-|---|---|---|
-| `EnvelopeGenerator.API` | net8.0 | ASP.NET Core Web API. Backend for **both Senders & Receivers**. Auth, PDF serving, signature endpoints. |
-| `EnvelopeGenerator.ReceiverUI` | net8.0 WASM | **Unified Blazor WebAssembly Frontend**. UI for **both Senders & Receivers**. YARP proxy to API. |
-| `EnvelopeGenerator.Web` | net7/8/9 | **DEPRECATED.** Legacy Razor Pages (Sender UI). No longer used. |
-| `EnvelopeGenerator.Application` | multi | MediatR CQRS handlers. Business logic. |
-| `EnvelopeGenerator.Domain` | multi | Domain models, constants, interfaces. |
-| `EnvelopeGenerator.Infrastructure` | multi | EF Core repos, DB context. |
-| `EnvelopeGenerator.PdfEditor` | multi | iText7 utilities (NOT used in ReceiverUI). |
-| `EnvelopeGenerator.DependencyInjection` | multi | DI registration helpers. |
-| **VB.NET projects** (Service/Form/BBTests) | net462 | **Legacy. Do NOT touch.** |

-
----
-
-## Coordinate System — CRITICAL
-
-**Database Format:** INCHES (GdPicture14 native)  
-**Origin:** Top-left corner  
-**Axes:** X right, Y down
-
-### Conversion Formulas
-
-| From INCHES to | Formula | Example |
-|---|---|---|
-| **DevExpress DX** | `x_DX = x_inches * 100` | 1.5" ? 150 DX |
-| **PDF Points** | `x_pt = x_inches * 72` | 1.5" ? 108 pt |
-| **PDF.js Pixels** | Normalize ? scale | `(x_inches / pageWidth) * canvasWidth * scale` |
-
-**A4 Dimensions:**
-- Width: 8.27" = 595pt = 827 DX
-- Height: 11.69" = 842pt = 1169 DX
-
-### Unit Systems
-
-| System | Unit | Origin | Y-Axis |
-|---|---|---|---|
-| **Database (GdPicture14)** | Inches | Top-left | Down |
-| PDF.js | Pixels | Top-left | Down |
-| iText7 PDF | Points (1/72") | **Bottom-left** | **Up** (flip required) |
-| ~~PSPDFKit~~ | ~~Points~~ | ~~Top-left~~ | **REMOVED** |

-
-## EnvelopeReceiver — PDF.js Viewer & Signing
-
-**Route:** `/envelope/{EnvelopeKey}`  
-**Tech:** PDF.js 3.11.174 + Blazor WASM + configurable quality  
-**File:** `ReceiverUI/Pages/EnvelopeReceiverPage.razor`
-
-### Key Features
-1. HiDPI/Retina support (4x quality)
-2. Configurable quality (`appsettings.json`)
-3. Unlimited zoom (50%-300%)
-4. Ctrl+Wheel global zoom
-5. Resizable thumbnail sidebar (150-400px, localStorage)
-6. Responsive (desktop/mobile)
-
-### Configuration
-**File:** `ReceiverUI/wwwroot/appsettings.json`
-
-```json
-{
-  "PdfViewer": {
-    "ThumbnailBaseScale": 0.75,
-    "ThumbnailEnableHiDPI": true,
-    "MainCanvasEnableHiDPI": true,
-    "ZoomStepPercentage": 5
-  }
-}
-```
-
-### JavaScript API
-**File:** `ReceiverUI/wwwroot/js/pdf-viewer.js`
-
-```javascript
-window.pdfViewer = {
-    initialize(canvasId, pdfDataUrl, dotNetRef),
-    renderPage(num),
-    renderSignatureButtons(signatures, pageNum, dotNetRef),
-    applySignature(signatureId, dataUrl, fullName, position, place),
-    zoomIn(), zoomOut(), dispose()
-}
-```
-
----
-
-## Signature Workflow — EnvelopeReceiver
-
-**IMPORTANT:** iText7 NOT used (GPL license issue). Client-side overlay system only.
-
-### Workflow Steps
-
-1. **Page Load:**
-   - Check `SignatureCacheService` for cached signature
-   - If cached ? skip popup, load signature
-   - If not ? show automatic popup (mandatory)
-
-2. **Signature Popup (DxPopup):**
-   - **Cannot close** (no X, no ESC, no outside-click)
-   - **3 Tabs:** Draw (canvas) / Text (font select) / Image (upload)
-   - **Required:** Full name, Place
-   - **Optional:** Position
-   - **Save ?** Store in `_capturedSignature`, cache via API
-
-3. **Signature Buttons:**
-   - Render purple "Unterschreiben" buttons at signature field positions
-   - Coordinates: INCHES ? POINTS ? Pixels (scaled)
-   - File: `pdf-viewer.js` ? `renderSignatureButtons()`
-
-4. **Apply Signature (Click "Unterschreiben"):**
-   - JS: Remove button, create HTML overlay
-   - Format: Image + separator + text (Name, Position, Place, Date)
-   - **NOT stamped on PDF bytes** (visual overlay only)
-
-5. **Re-rendering:**
-   - Zoom/Page change ? recalculate button positions
-   - Session state: `_capturedSignature` (lost on refresh)
-
-### Data Model
-**File:** `ReceiverUI/Models/SignatureCaptureDto.cs`
-
-```csharp
-public sealed record SignatureCaptureDto {
-    public required string DataUrl { get; init; }    // base64 PNG
-    public required string FullName { get; init; }
-    public string Position { get; init; } = "";      // Optional
-    public required string Place { get; init; }
-}
-```
-
----
-
-## Signature Caching
-
-**Purpose:** Persist signature across page refreshes (distributed cache: Redis/SQL)
-
-### API Endpoints
-**Controller:** `API/Controllers/CacheController.cs`
-
-- `POST /api/Cache/SignatureCapture/{envelopeKey}` — Save
-- `GET /api/Cache/SignatureCapture/{envelopeKey}` — Load
-- `DELETE /api/Cache/SignatureCapture/{envelopeKey}` — Delete
-
-**Cache Key Format:**
-```
-signature:91751687-8ae6-4777-bf5f-b8846085e62e:{envelopeKey}
-```
-
-**Configuration:** `appsettings.json`
-```json
-{
-  "Cache": {
-    "SignatureCacheExpiration": null  // or "02:00:00" for 2h
-  }
-}
-```
-
-### Service
-**File:** `ReceiverUI/Services/SignatureCacheService.cs`
-
-```csharp
-public class SignatureCacheService {
-    Task SaveSignatureAsync(string envelopeKey, SignatureCaptureDto signature);
-    Task<SignatureCaptureDto?> GetSignatureAsync(string envelopeKey);
-    Task DeleteSignatureAsync(string envelopeKey);
-}
-```
-
-**Error Handling:** Fire-and-forget saves, graceful degradation on load failure.
-
----
-
-## Sender Login
-
-**Route:** `/sender/login`  
-**File:** `ReceiverUI/Pages/LoginSenderPage.razor`  
-**Tech:** Bootstrap 5 + DevExpress Blazing Berry theme
-
-### AuthService Extension
-**File:** `ReceiverUI/Services/AuthService.cs`
-
-```csharp
-public enum SenderLoginResult { Success, InvalidCredentials, Error }
-
-public async Task<SenderLoginResult> LoginSenderAsync(string username, string password) {
-    var response = await http.PostAsJsonAsync(
-        $"{_api.BaseUrl}/api/auth?cookie=true",
-        new { username, password });
-    
-    return response.StatusCode switch {
-        HttpStatusCode.OK => SenderLoginResult.Success,
-        HttpStatusCode.Unauthorized => SenderLoginResult.InvalidCredentials,
-        _ => SenderLoginResult.Error
-    };
-}
-```
-
-### API Integration
-**Endpoint:** `POST /api/auth?cookie=true`
-
-**Request:**
-```json
-{ "username": "TekH", "password": "***" }
-```
-
-**Response:**
-- `200 OK` ? Cookie set, redirect to `/sender`
-- `401 Unauthorized` ? Show error: "Ungültige Anmeldedaten"
-- Other ? Show error: "Serverfehler"
-
-**Cookie:** HTTP-only, Secure (HTTPS), SameSite=Strict
-
-### UI Flow
-1. User enters username + password
-2. Click "Anmelden" or press Enter
-3. Call `AuthService.LoginSenderAsync()`
-4. Success ? `Navigation.NavigateTo("/sender", forceLoad: true)`
-5. Error ? Display alert
-
----
-
-## Receiver Login
-
-**Route:** `/envelope/login/{EnvelopeKey}`  
-**File:** `ReceiverUI/Pages/LoginReceiverPage.razor`
-
-**Multi-Envelope Support:** Cookies are stored per-envelope (e.g., `AuthTokenSignFLOWReceiver.{envelopeKey}`), allowing simultaneous authentication for multiple envelopes in the same browser session.
-
-### AuthService Method
-```csharp
-public enum EnvelopeLoginResult { Success, InvalidCode, NotFound, Error }
-
-public async Task<EnvelopeLoginResult> LoginEnvelopeReceiverAsync(string key, string accessCode) {
-    var form = new MultipartFormDataContent();
-    form.Add(new StringContent(accessCode), "AccessCode");
-    
-    var response = await http.PostAsync(
-        $"{_api.BaseUrl}/api/Auth/envelope-receiver/{Uri.EscapeDataString(key)}", form);
-    
-    return response.StatusCode switch {
-        HttpStatusCode.OK => EnvelopeLoginResult.Success,
-        HttpStatusCode.Unauthorized => EnvelopeLoginResult.InvalidCode,
-        HttpStatusCode.NotFound => EnvelopeLoginResult.NotFound,
-        _ => EnvelopeLoginResult.Error
-    };
-}
-```
-
-**Success:** Redirect to `/envelope/{key}`
-

-| `DevExpress.Blazor.*` | 25.2.3 | UI components (grids, popups, etc.) |
-| `SkiaSharp.*` | 3.119.1 | WASM rendering |
-| ~~`itext`~~ | ~~8.0.5~~ | **NOT USED** (GPL license) |

-
-## Mistakes History — Do NOT Repeat
-
-| Mistake | Why Wrong |
-|---|---|
-| Using iText7 in EnvelopeReceiver | GPL license issue. Use overlay system instead. |
-| Using PSPDFKit | Removed from architecture. Use PDF.js + DevExpress. |
-| Hardcoded quality values in PDF.js | Use `appsettings.json` for configurability. |
-| Complex toolbar layouts | User wants simplicity. Keep horizontal layout. |
-| Over-designed UI (gradients/badges) | User prefers simple text labels. |
-| Ignoring "revert" instructions | Revert HTML structure, not just CSS. |
-| `BottomMarginBand` for signatures | Repeats on every page. Use DetailBand. |
-| `imageY = (page-1) * 1169 + ann.Y` | Inflates DetailBand. Calculate per-page. |
-

-
-## Development Notes
-
-### Deprecated Projects
-**DO NOT USE:**
-- `EnvelopeGenerator.Web` (Razor Pages) — Replaced by unified ReceiverUI
-- PSPDFKit — Removed, use PDF.js + DevExpress instead
-
-### Legacy Projects (VB.NET)
-**DO NOT TOUCH:** `EnvelopeGenerator.Service`, `EnvelopeGenerator.Form`, `EnvelopeGenerator.BBTests`
-
-### Signature Coordinate Evidence
-**File:** `EnvelopeGenerator.Form/frmFieldEditor.vb` (VB.NET)
-
-```vb
-Private Const SIGNATURE_WIDTH As Single = 1.77   ' inches
-Private Const SIGNATURE_HEIGHT As Single = 1.96  ' inches
-
-Sub LoadAnnotation(pElement As Signature, ...)
-    oAnnotation.Left = CSng(pElement.X)    ' Direct INCHES assignment
-    oAnnotation.Top = CSng(pElement.Y)
-End Sub
-```
-
-Proves database uses INCHES natively.
-
----
-
-## Quick Reference
-
-### When working with coordinates:
-1. **Database ? UI:** INCHES × 72 = PDF Points
-2. **UI ? Display:** Points × scale = Pixels
-3. **iText7 stamping:** Flip Y-axis (top-down ? bottom-up)
-
-### When adding features:
-1. Check `Mistakes History` first
-2. Prefer simplicity over complexity
-3. Use `appsettings.json` for configuration
-4. Keep consistent with existing design (Bootstrap 5 + Blazing Berry)
-5. **Unified frontend:** ReceiverUI serves both Senders and Receivers
-
-### When debugging:
-1. **Coordinates:** Always check unit system (inches/points/pixels)
-2. **Authentication:** Check cookie name/domain/SameSite
-3. **Cache:** Check Redis/SQL connection + key format
-4. **Frontend confusion:** Only use ReceiverUI (Web is deprecated)
-
