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
