feat(sender): add envelope delete popup and client call

Updated SF-74-PLAN.md to document completed phases (6a–6e), including theme selection, dark mode, grid persistence, and logo placement. Highlighted pending tasks for phase 6f and clarified open questions.

Revised MIGRATION_PLAN.md with deep analysis findings and detailed steps for migrating `EnvelopeGenerator.Service_legacy` to a modern C# Worker Service. Addressed connection string handling, Quartz version mismatch, and TempFiles architecture.

Removed outdated markdown files from EnvelopeGenerator.sln and updated the solution structure for consistency.

Fixed incorrect "Read and confirmed" label in Signature Certificate reports for "Read and Sign" envelopes. Added branching logic in `ReportItem.vb` and updated resource files.

Resolved signature field formatting issues in finalized PDFs based on WISAG feedback. Added truncation logic in `PDFBurner.vb` and updated `PDFBurnerParams.vb` with per-field character limits.

+
+## Documentation Catalog
+
+This section explains every markdown file in the repo: what it contains, why it exists, and when you need it. Read this before deciding which file to open.
+
+### Core Architecture Docs (Active — Always Relevant)
+
+#### `AGENTS.md` ← you are here
+**What:** Authoritative agent/copilot onboarding guide. Covers project structure, route table, render mode rules, coordinate system, API gaps, and common mistakes.
+**Why it exists:** Single source of truth for agents so they don't re-derive architecture from code on every session.
+**When you need it:** Always. Read first on every session.
+**Maintenance:** Update whenever project structure, routes, render modes, or naming conventions change.
+
+#### `COPILOT_CONTEXT.md`
+**What:** Deep-dive architecture reference. Covers the full Blazor Auto hybrid setup, authentication flows (JWT + cookies, per-envelope receiver tokens), service registration patterns, coordinate system proof, and an explicit "prefer Server/Server.Client over old WebUI/ReceiverUI" rule.
+**Why it exists:** Prevents agents from re-deriving or misinterpreting the hybrid SSR+WASM architecture. Also documents coordinate system evidence to prevent regressions (inches vs. points vs. pixels).
+**When you need it:**
+- Implementing any new page or service
+- Debugging auth/cookie issues
+- Any coordinate conversion question
+- Unsure which project a new file should go in
+**Maintenance:** Update when render mode assignments change, new auth schemes are added, or the coordinate system is touched.
+
+#### `FORM_APPLICATION_CONTEXT.md`
+**What:** Comprehensive reverse-engineering of the legacy VB.NET WinForms app (`EnvelopeGenerator.Form`). Documents every form (frmMain, frmEnvelopeEditor, frmFieldEditor, etc.), their UI layout, toolbar actions, data models, coordinate system, and a feature-by-feature migration mapping table to `EnvelopeGenerator.Server`.
+**Why it exists:** The WinForms app is the functional specification for the sender-side web UI. It documents the full intended workflow that is being migrated to Blazor — especially the envelope creation, signature field placement, and dashboard features that are not yet implemented.
+**When you need it:**
+- Implementing any sender-side feature (`/sender`, `/sender/editor`, `/sender/envelope/{id}`)
+- Understanding what a specific toolbar button or form should do
+- Designing API endpoints for sender workflow
+- Checking coordinate system behavior (INCHES proof is here)
+**Maintenance:** Update the mapping table as features are implemented (change `❌ Not implemented` → `✅ Exists`). Do not rename `ReceiverUI` back — it was the old project name; current target is `EnvelopeGenerator.Server`.
+
+#### `RECEIVER_PDF_VIEWER_CONTEXT.md`
+**What:** Detailed technical reference for the receiver-side PDF viewer (`EnvelopeReceiverPage.razor`). Documents the PDF.js integration, signature button rendering, JS interop API (`window.pdfViewer`), signature capture flow, HiDPI/zoom/thumbnail config, and the full component lifecycle.
+**Why it exists:** The receiver PDF viewer is the most complex component in the codebase. This doc prevents agents from misunderstanding the JS↔Blazor boundary, re-implementing already-solved problems (HiDPI, zoom, signature caching), or breaking the signing flow.
+**When you need it:**
+- Working on `EnvelopeReceiverPage.razor` or `pdf-viewer.js`
+- Adding new signature field rendering logic
+- Debugging signature rendering, zoom, or thumbnail issues
+- Implementing sender-side PDF.js overlay (signature field placement) — the receiver side is the reference implementation
+**Maintenance:** Update when `pdf-viewer.js` API changes, new JS interop functions are added, or the signing flow is modified.
+
+---
+
+### Deployment Docs
+
+#### `EnvelopeGenerator.Server/EnvelopeGenerator.Server/README.md`
+**What:** IIS publish and deployment guide for `EnvelopeGenerator.Server`. Covers why self-contained publish is required (WASM assembly version strictness), the exact `dotnet publish` command, IIS Application Pool settings (`No Managed Code`), directory structure after publish, and common deployment errors.
+**Why it exists:** Blazor Auto (Server + WASM hybrid) has non-obvious deployment requirements that differ from a standard ASP.NET Core app. Forgetting self-contained publish or using the wrong app pool will break WASM loading in production.
+**When you need it:**
+- Deploying to IIS for the first time
+- Troubleshooting 500 errors on production after deploy
+- Setting up a new deployment environment
+**Maintenance:** Update if the publish target, IIS config, or runtime version changes.
+
+---

+- **EnvelopeGenerator.Server** (Server): `@rendermode InteractiveServer` - PDF viewers requiring DevExpress backend
+- **EnvelopeGenerator.Server.Client** (WASM): `@rendermode InteractiveWebAssembly` - Login, dashboards, business logic

-    Microsoft ResX Schema 
-    
-    Version 2.0
-    
-    The primary goals of this format is to allow a simple XML format 
-    that is mostly human readable. The generation and parsing of the 
-    various data types are done through the TypeConverter classes 
-    associated with the data types.
-    
-    Example:
-    
-    ... ado.net/XML headers & schema ...
-    <resheader name="resmimetype">text/microsoft-resx</resheader>
-    <resheader name="version">2.0</resheader>
-    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
-    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
-    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
-    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
-    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
-        <value>[base64 mime encoded serialized .NET Framework object]</value>
-    </data>
-    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
-        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
-        <comment>This is a comment</comment>
-    </data>
-                
-    There are any number of "resheader" rows that contain simple 
-    name/value pairs.
-    
-    Each data row contains a name, and value. The row also contains a 
-    type or mimetype. Type corresponds to a .NET class that support 
-    text/value conversion through the TypeConverter architecture. 
-    Classes that don't support this are serialized and stored with the 
-    mimetype set.
-    
-    The mimetype is used for serialized objects, and tells the 
-    ResXResourceReader how to depersist the object. This is currently not 
-    extensible. For a given mimetype the value must be set accordingly:
-    
-    Note - application/x-microsoft.net.object.binary.base64 is the format 
-    that the ResXResourceWriter will generate, however the reader can 
-    read any of the formats listed below.
-    
-    mimetype: application/x-microsoft.net.object.binary.base64
-    value   : The object must be serialized with 
-            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
-            : and then encoded with base64 encoding.
-    
-    mimetype: application/x-microsoft.net.object.soap.base64
-    value   : The object must be serialized with 
-            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
-            : and then encoded with base64 encoding.
-
-    mimetype: application/x-microsoft.net.object.bytearray.base64
-    value   : The object must be serialized into a byte array 
-            : using a System.ComponentModel.TypeConverter
-            : and then encoded with base64 encoding.

-// ⚠️ TODO: REMOVE/REFACTOR WHEN MIGRATING TO BLAZOR SERVER/AUTO
-// In Server/Auto render modes, this is DANGEROUS because:
-// - Server runs a single shared instance for all users
-// - Setting global culture affects ALL connected users simultaneously
-// - Race conditions and culture conflicts will occur
-//
-// Migration Guide:
-// - Option 1: Use RequestLocalizationMiddleware for per-request culture
-// - Option 2: Use CascadingParameter with per-circuit culture state
-// - See: https://learn.microsoft.com/aspnet/core/blazor/globalization-localization
-//
-// Related files to update on migration:
-// - LanguageSelector.razor (remove manual culture setting)
-// - App.razor (may need CascadingValue for culture)
-// - Startup/Program.cs (add middleware)

-
-### General Usage
-
-#### Using Open Iconic's SVGs
-
-We like SVGs and we think they're the way to display icons on the web. Since Open Iconic are just basic SVGs, we suggest you display them like you would any other image (don't forget the `alt` attribute).
-
-```
-<img src="/open-iconic/svg/icon-name.svg" alt="icon name">
-```
-
-#### Using Open Iconic's SVG Sprite
-
-Open Iconic also comes in a SVG sprite which allows you to display all the icons in the set with a single request. It's like an icon font, without being a hack.
-
-Adding an icon from an SVG sprite is a little different than what you're used to, but it's still a piece of cake. *Tip: To make your icons easily style able, we suggest adding a general class to the* `<svg>` *tag and a unique class name for each different icon in the* `<use>` *tag.*  
-
-```
-<svg class="icon">
-  <use xlink:href="open-iconic.svg#account-login" class="icon-account-login"></use>
-</svg>
-```
-
-Sizing icons only needs basic CSS. All the icons are in a square format, so just set the `<svg>` tag with equal width and height dimensions.
-
-```
-.icon {
-  width: 16px;
-  height: 16px;
-}
-```
-
-Coloring icons is even easier. All you need to do is set the `fill` rule on the `<use>` tag.
-
-```
-.icon-account-login {
-  fill: #f00;
-}
-```
