Fix label for "Read and Sign" envelopes in reports

Addressed an issue where the Signature Certificate report incorrectly displayed "Document signed" for "Read and Sign" envelopes. Added a new resource key, `DocumentSignedRaC`, with translations ("Read and confirmed" / "Gelesen und bestätigt") to resolve this.

Updated `ItemStatusTranslated` in `ReportItem.vb` to use the new key for "Read and Sign" envelopes (`EnvelopeTypeId == 2`) while retaining existing behavior for other envelope types. Leveraged `Envelope.IsReadAndConfirm()` to determine envelope type.

Pending tasks include adding the new resource key to resource files and updating `Model.Designer.cs` with a strongly-typed property. Testing instructions provided to verify correct label behavior.

+# Fix: Report Label "Read and confirmed" for Read and Sign Envelopes
+
+## Status
+?? **IN PROGRESS**
+
+## Git Branch
+```
+fix/report-label-read-and-confirmed
+```
+
+---
+
+## Problem
+
+In the **Signature Certificate report** (`Signierungszertifikat`), the history event
+list always showed **"Document signed"** for status `DocumentSigned` (code `2005`) —
+even when the envelope type was **"Read and Sign"** (`EnvelopeTypeId = 2`).
+
+For "Read and Sign" envelopes the correct label must be **"Read and confirmed"**
+(DE: **"Gelesen und bestätigt"**).
+
+### Screenshot reference
+The report shows a table with columns *Ereignis | Benutzer | Zeitstempel*.  
+The row with status 2005 displayed "Document signed" where "Read and confirmed"
+was expected.
+
+---
+
+## Root Cause
+
+`ReportItem.ItemStatusTranslated` in
+`EnvelopeGenerator.CommonServices\Jobs\FinalizeDocument\ReportItem.vb`
+resolved the display label by calling:
+
+```vb
+My.Resources.Model.ResourceManager.GetString(ItemStatus.ToString())
+```
+
+There was **no branching logic** to handle the Read and Sign envelope type.
+The same `DocumentSigned` key was always used regardless of envelope type.
+
+---
+
+## Solution
+
+### Convention followed
+The project already uses a `RaC` (**R**ead **a**nd **C**onfirm) suffix for
+Read-and-Sign label variants across all resource files:
+
+| Existing RaC keys |
+|---|
+| `DocumentRejectedRaC` |
+| `EnvelopeReportCreatedRaC` |
+| `MessageConfirmationSentRaC` |
+
+### New resource key added: `DocumentSignedRaC`
+
+| Resource file | Value |
+|---|---|
+| `Model.resx` (DE, default) | `Gelesen und bestätigt` |
+| `Model.en.resx` (EN) | `Read and confirmed` |
+
+### Logic change in `ReportItem.vb`
+
+```vb
+Public ReadOnly Property ItemStatusTranslated As String
+    Get
+        Dim oStatusKey = ItemStatus.ToString()
+
+        If ItemStatus = EnvelopeStatus.DocumentSigned AndAlso
+           Envelope IsNot Nothing AndAlso
+           Envelope.IsReadAndConfirm() Then
+            oStatusKey = "DocumentSignedRaC"
+        End If
+
+        Return My.Resources.Model.ResourceManager.GetString(oStatusKey)
+    End Get
+End Property
+```
+
+`Envelope.IsReadAndConfirm()` is defined in
+`EnvelopeGenerator.Domain\Interfaces\IEnvelope.cs` and returns `true`
+when `EnvelopeTypeId == 2`.
+

+
+## Files Changed
+
+| # | File | Change | Status |
+|---|---|---|---|
+| 1 | `EnvelopeGenerator.CommonServices\Jobs\FinalizeDocument\ReportItem.vb` | Added `RaC` branching logic to `ItemStatusTranslated` | ? Done |
+| 2 | `EnvelopeGenerator.Domain\Resources\Model.resx` | Added `DocumentSignedRaC` = `Gelesen und bestätigt` | ?? Pending |
+| 3 | `EnvelopeGenerator.CommonServices\Strings\Model.resx` | Added `DocumentSignedRaC` = `Gelesen und bestätigt` | ?? Pending |
+| 4 | `EnvelopeGenerator.CommonServices\Strings\Model.en.resx` | Added `DocumentSignedRaC` = `Read and confirmed` | ?? Pending |
+| 5 | `EnvelopeGenerator.Domain\Resources\Model.Designer.cs` | Added `DocumentSignedRaC` strongly-typed property | ?? Pending |
+
+---
+
+## How to resume (for next agent)
+
+All pending items are **resource file additions only**.  
+Each file needs one new `<data>` block inserted **directly after** the existing
+`DocumentSigned` entry:
+
+```xml
+<data name="DocumentSignedRaC" xml:space="preserve">
+  <value>Gelesen und bestätigt</value>   <!-- DE files -->
+  <!-- OR -->
+  <value>Read and confirmed</value>       <!-- EN file -->
+</data>
+```
+
+`Model.Designer.cs` also needs a new strongly-typed property added after
+`DocumentSigned`:
+
+```csharp
+/// <summary>
+///   Looks up a localized string similar to Gelesen und bestätigt.
+/// </summary>
+public static string DocumentSignedRaC {
+    get {
+        return ResourceManager.GetString("DocumentSignedRaC", resourceCulture);
+    }
+}
+```
+
+---
+
+## Testing
+
+After changes, generate a Signature Certificate report for a **Read and Sign**
+envelope and verify:
+- History row with status 2005 shows **"Read and confirmed"** (EN)
+- History row with status 2005 shows **"Gelesen und bestätigt"** (DE)
+- Regular (non-RaC) envelopes still show **"Document signed"** / **"Dokument unterzeichnet"**
