feat: add Qobuz playlist caching with versioning and infinite scroll UI

- Add qobuz_debug to .gitignore
- Bump PMOMusic version to 0.3.26
- Add .cargo/ copy in Dockerfile for registry config
- Implement infinite scroll in ServerDrawer.vue with IntersectionObserver and sentinel element
- Add source/source_version fields to playlists for cache invalidation
- Update pmocache and pmoplaylist DB schemas with versioning (SCHEMA_VERSION)
- Add Qobuz API metadata fetching and pagination for playlist tracks
- Implement album/playlist cache invalidation based on released_at/updated_at timestamps
- Refactor adapt_playlist_items_to_qobuz → adapt_items_to_qobuz with cleaner logic
- Add debug mode to save Qobuz API responses when QOBUZ_DEBUG_DIR is set
