Updated Dockerfile, entrypoint.sh, and Python code to store database files in /app/data instead of /app/database, avoiding conflicts with the Python package. The database path is now configurable via the DATABASE_PATH environment variable, improving flexibility for container deployments.
Implements manual track matching (discovery fix modal) for YouTube, Tidal, and Beatport platforms, allowing users to search and select Spotify tracks for unmatched results. Adds backend endpoints and frontend logic for updating matches, improves conversion of discovery results for sync/download, and updates Dockerfile/entrypoint for dynamic PUID/PGID/UMASK support. Includes a new DOCKER_PERMISSIONS.md guide.
