Cursor Agent 1e5451859f fix: resolve gray screens and add automatic versioning
1. Fix Downloads screen gray screen issue:
   - Add DownloadsProvider to main.dart providers list
   - Remove @RoutePage() decorator from DownloadsScreen
   - Downloads screen now displays torrent list correctly

2. Fix movie detail screen gray screen issue:
   - Improve Movie.fromJson() with better error handling
   - Safe parsing of genres field (handles both Map and String formats)
   - Add fallback 'Untitled' for movies without title
   - Add detailed logging in MovieDetailProvider
   - Better error messages with stack traces

3. Add automatic version update from CI/CD tags:
   - GitLab CI: Update pubspec.yaml version from CI_COMMIT_TAG before build
   - GitHub Actions: Update pubspec.yaml version from GITHUB_REF before build
   - Version format: tag v0.0.18 becomes version 0.0.18+18
   - Applies to all build jobs (arm64, arm32, x64)

How versioning works:
- When you create tag v0.0.18, CI automatically updates pubspec.yaml
- Build uses version 0.0.18+18 (version+buildNumber)
- APK shows correct version in About screen and Google Play
- No manual pubspec.yaml updates needed

Example:
- Create tag: git tag v0.0.18 && git push origin v0.0.18
- CI reads tag, extracts '0.0.18'
- Updates: version: 0.0.18+18 in pubspec.yaml
- Builds APK with this version
- Release created with proper version number

Changes:
- lib/main.dart: Add DownloadsProvider
- lib/presentation/screens/downloads/downloads_screen.dart: Remove @RoutePage
- lib/data/models/movie.dart: Safe JSON parsing with error handling
- lib/presentation/providers/movie_detail_provider.dart: Add detailed logging
- .gitlab-ci.yml: Add version update script in all build jobs
- .github/workflows/release.yml: Add version update step in all build jobs

Result:
 Downloads screen displays properly
 Movie details screen loads correctly
 Automatic versioning from tags (0.0.18, 0.0.19, etc.)
 No more gray screens!
