personal certs working

**Backend fixes:**
- SigningSessionController: Gracefully skip SERVER certificate type when feature unavailable
- Change createSession endpoint to return ResponseEntity<SigningSession> with JSON content type
- Prevents errors in non-proprietary/unlicensed deployments

**Frontend enhancements:**
- SigningWorkflow: Auto-detect JSON session files and skip to finalization
- Add JSON file support to tool registry (supportedFormats: pdf, json)
- Enable session owners to re-upload JSON and finalize without recreating
- Debug logging for troubleshooting session detection

**Routing:**
- Core App.tsx: Add query param detection for participant URLs
- Proprietary App.tsx: Add /signing-session route with React Router integration
- Both apps now support: /signing-session?sessionId={id}&token={token}

**Complete end-to-end workflow:**
1. Owner creates session → downloads JSON with participant tokens
2. Participants access unique URLs → submit certificates (PEM/PKCS12/PFX/JKS)
3. Owner re-uploads JSON → clicks finalize → downloads signed PDF
4. SERVER certificate type gracefully skipped when feature unavailable

+# Windows Code Signing Setup Guide
+
+This guide explains how to set up Windows code signing for Stirling-PDF desktop application builds.
+
+## Overview
+
+Windows code signing is essential for:
+- Preventing Windows SmartScreen warnings
+- Building trust with users
+- Enabling Microsoft Store distribution
+- Professional application distribution
+
+## Certificate Types
+
+### OV Certificate (Organization Validated)
+- More affordable option
+- Requires business verification
+- May trigger SmartScreen warnings initially until reputation builds
+- Suitable for most independent software vendors
+
+### EV Certificate (Extended Validation)
+- Premium option with immediate SmartScreen reputation
+- Requires hardware security module (HSM) or cloud-based signing
+- Higher cost but provides immediate trust
+- Required since June 2023 for new certificates
+
+## Obtaining a Certificate
+
+### Certificate Authorities
+Popular certificate authorities for Windows code signing:
+- DigiCert
+- Sectigo (formerly Comodo)
+- GlobalSign
+- SSL.com
+
+### Certificate Format
+You'll receive a certificate in one of these formats:
+- `.pfx` or `.p12` (preferred - contains both certificate and private key)
+- `.cer` + private key (needs conversion to .pfx)
+
+### Converting to PFX (if needed)
+If you have separate certificate and private key files:
+
+```bash
+openssl pkcs12 -export -out certificate.pfx -inkey private-key.key -in certificate.cer
+```
+
+## Setting Up GitHub Secrets
+
+### Required Secrets
+
+Navigate to your GitHub repository → Settings → Secrets and variables → Actions
+
+Add the following secrets:
+
+#### 1. `WINDOWS_CERTIFICATE`
+- **Description**: Base64-encoded .pfx certificate file
+- **How to create**:
+
+**On macOS/Linux:**
+```bash
+base64 -i certificate.pfx | pbcopy  # Copies to clipboard
+```
+
+**On Windows (PowerShell):**
+```powershell
+[Convert]::ToBase64String([IO.File]::ReadAllBytes("certificate.pfx")) | Set-Clipboard
+```
+
+Paste the entire base64 string into the GitHub secret.
+
+#### 2. `WINDOWS_CERTIFICATE_PASSWORD`
+- **Description**: Password for the .pfx certificate
+- **Value**: The password you set when creating/exporting the .pfx file
+
+### Optional Secrets for Tauri Updater
+
+If you're using Tauri's built-in updater feature:
+
+#### `TAURI_SIGNING_PRIVATE_KEY`
+- Generated using Tauri CLI: `npm run tauri signer generate`
+- Used for update package verification
+
+#### `TAURI_SIGNING_PRIVATE_KEY_PASSWORD`
+- Password for the Tauri signing key
+
+## Configuration Files
+
+### 1. Tauri Configuration (frontend/src-tauri/tauri.conf.json)
+
+The Windows signing configuration is already set up:
+
+```json
+"windows": {
+  "certificateThumbprint": null,
+  "digestAlgorithm": "sha256",
+  "timestampUrl": "http://timestamp.digicert.com"
+}
+```
+
+**Configuration Options:**
+- `certificateThumbprint`: Automatically extracted from imported certificate (leave as `null`)
+- `digestAlgorithm`: Hashing algorithm - `sha256` is recommended
+- `timestampUrl`: Timestamp server to prove signing time (survives certificate expiration)
+
+**Alternative Timestamp Servers:**
+- DigiCert: `http://timestamp.digicert.com`
+- Sectigo: `http://timestamp.sectigo.com`
+- GlobalSign: `http://timestamp.globalsign.com`
+
+### 2. GitHub Workflow (.github/workflows/tauri-build.yml)
+
+The workflow includes three Windows signing steps:
+
+1. **Import Certificate**: Decodes and imports the .pfx certificate into Windows certificate store
+2. **Build Tauri App**: Builds and signs the application using the imported certificate
+3. **Verify Signature**: Validates that both .exe and .msi files are properly signed
+
+## Testing the Setup
+
+### 1. Local Testing (Windows Only)
+
+Before pushing to GitHub, test locally:
+
+```powershell
+# Set environment variables
+$env:WINDOWS_CERTIFICATE = [Convert]::ToBase64String([IO.File]::ReadAllBytes("certificate.pfx"))
+$env:WINDOWS_CERTIFICATE_PASSWORD = "your-certificate-password"
+
+# Build the application
+cd frontend
+npm run tauri build
+
+# Verify the signature
+Get-AuthenticodeSignature "./src-tauri/target/release/bundle/msi/Stirling-PDF_*.msi"
+```
+
+### 2. GitHub Actions Testing
+
+1. Push your changes to a branch
+2. Manually trigger the workflow:
+   - Go to Actions → Build Tauri Applications
+   - Click "Run workflow"
+   - Select "windows" platform
+3. Check the build logs for:
+   - ✅ Certificate import success
+   - ✅ Build completion
+   - ✅ Signature verification
+
+### 3. Verifying Signed Binaries
+
+After downloading the built artifacts:
+
+**Windows (PowerShell):**
+```powershell
+Get-AuthenticodeSignature "Stirling-PDF-windows-x86_64.exe"
+Get-AuthenticodeSignature "Stirling-PDF-windows-x86_64.msi"
+```
+
+Look for:
+- Status: `Valid`
+- Signer: Your organization name
+- Timestamp: Recent date/time
+
+**Windows (GUI):**
+1. Right-click the .exe or .msi file
+2. Select "Properties"
+3. Go to "Digital Signatures" tab
+4. Verify signature details
+
+## Troubleshooting
+
+### "HashMismatch" Status
+- Certificate doesn't match the binary
+- Possible file corruption during download
+- Re-download and verify
+
+### "NotSigned" Status
+- Certificate wasn't imported correctly
+- Check GitHub secrets are set correctly
+- Verify base64 encoding is complete (no truncation)
+
+### "UnknownError" Status
+- Timestamp server unreachable
+- Try alternative timestamp URL in tauri.conf.json
+- Check network connectivity in GitHub Actions
+
+### SmartScreen Still Shows Warnings
+- Normal for OV certificates initially
+- Reputation builds over time with user downloads
+- Consider EV certificate for immediate reputation
+
+### Certificate Not Found During Build
+- Verify `WINDOWS_CERTIFICATE` secret is set
+- Check base64 encoding is correct (no extra whitespace)
+- Ensure password is correct
+
+## Security Best Practices
+
+1. **Never commit certificates to version control**
+   - Keep .pfx files secure and backed up
+   - Use GitHub secrets for CI/CD
+
+2. **Rotate certificates before expiration**
+   - Set calendar reminders
+   - Update GitHub secrets with new certificate
+
+3. **Use strong passwords**
+   - Certificate password should be complex
+   - Store securely (password manager)
+
+4. **Monitor certificate usage**
+   - Review GitHub Actions logs
+   - Set up notifications for failed builds
+
+5. **Limit access to secrets**
+   - Only repository admins should access secrets
+   - Audit secret access regularly
+
+## Certificate Lifecycle
+
+### Before Expiration
+1. Obtain new certificate from CA (typically annual renewal)
+2. Convert to .pfx format if needed
+3. Update `WINDOWS_CERTIFICATE` secret with new base64-encoded certificate
+4. Update `WINDOWS_CERTIFICATE_PASSWORD` if password changed
+5. Test build to verify new certificate works
+
+### Expired Certificates
+- Signed binaries remain valid (timestamp proves signing time)
+- New builds will fail until certificate is renewed
+- Users can still install previously signed versions
+
+## Cost Considerations
+
+### Certificate Costs (Annual, as of 2024)
+- **OV Certificate**: $100-400/year
+- **EV Certificate**: $400-1000/year
+
+### Choosing the Right Certificate
+- **Open source / early stage**: Start with OV
+- **Commercial / enterprise**: Consider EV for better trust
+- **Microsoft Store**: EV certificate required

+
+## Support
+
+If you encounter issues with Windows code signing:
+1. Check GitHub Actions logs for detailed error messages
+2. Verify all secrets are set correctly
+3. Test certificate locally first (Windows environment required)
+4. Open an issue in the repository with relevant logs (remove sensitive data)
