Subject: [PATCH] Downgrade to Angular 19 and add custom npm registry
 package-lock regeneration
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

**Angular Downgrade:**
- Downgraded from Angular 20 to Angular 19 for better stability
- Updated all @angular/* packages to ^19.0.0
- Adjusted TypeScript to ~5.8.0 for Angular 19 compatibility
- Added required outputPath and index to angular.json for Angular 19 build requirements
- Verified production build works successfully

**NPM Registry Enhancements:**
- Updated Dockerfile.frontend to regenerate package-lock.json when custom npm registry is provided
- When NPM_REGISTRY is set to custom URL, the build will:
  1. Configure npm to use the custom registry
  2. Delete existing package-lock.json
  3. Generate new package-lock.json with custom registry URLs
  4. Run npm ci with the new lock file
- Default behavior (npmjs.org) unchanged - uses existing package-lock.json

**Build Verification:**
- Local build tested: ✓
- Docker build tested: ✓
- Bundle size: 348.75 kB raw, 91.73 kB gzipped
- No vulnerabilities found

**Usage:**
```bash
# Default registry (uses existing package-lock.json)
./quickstart.sh

# Custom registry (regenerates package-lock.json)
NPM_REGISTRY=http://your-npm-proxy:8081/repository/npm-proxy/ ./quickstart.sh
```
