feat: implement Live/Remix filtering and add CI/CD pipeline

This commit includes:

1. Live/Remix Filtering Feature:
   - Added ignore_live and ignore_remix columns to artist_settings table (migration 010)
   - Updated ArtistSettings struct with IgnoreLive and IgnoreRemix fields
   - Modified SaveArtistSettings and UpdateArtistSettings to handle new fields
   - Extended FilterOptions struct with IgnoreLive and IgnoreRemix
   - Updated ApplyTypeToggles and ApplyTypeTogglesToReleaseGroups to filter Live/Remix types
   - Added toggleIgnoreLive and toggleIgnoreRemix handlers in web layer
   - Updated ArtistData view model and artist.html template with new toggle UI
   - Comprehensive test coverage for all new functionality

2. CI/CD Pipeline with Gitea Actions:
   - Added .gitea/workflows/docker-build.yml for automated Docker builds
   - Workflow triggers on pushes to main/master and tags, plus PRs
   - Runs Go tests before building
   - Builds and pushes multi-architecture Docker images to gitea.mrixs.me
   - Includes caching for faster subsequent builds
   - Proper tagging strategy (branch, semver, SHA)
   - CI-CD-GUIDE.md documentation

3. Cleanup:
   - Removed temporary build artifacts and coverage files
