Add automated PostgreSQL performance index management
- Add scripts and SQL for base and supplementary indexes (total 23) - Integrate index checks and auto-creation into Jellyfin startup - Update csproj to include SQL files in build/publish output - Add diagnostics, publish/copy scripts, and troubleshooting docs - Provide detailed guides for migration, verification, and merging - Ensures robust, automated, and well-documented index setup
