Add scripts for PostgreSQL migration and SQLite removal; update project references

- Introduced `publish-with-sql.ps1` to publish Jellyfin with SQL files.
- Added `remove-sqlite.ps1` to facilitate the removal of SQLite dependencies for PostgreSQL-only deployment.
- Created `rollback-to-net10.ps1` to revert .NET 11 changes back to .NET 10.
- Implemented `test_api.py` for testing API interactions.
- Added `verify-migration.ps1` to verify PostgreSQL migration steps.
- Updated various `.csproj` files to include `Microsoft.Kiota.Abstractions` package.
- Enhanced `JellyfinDbContext` to handle concurrency exceptions during save operations.
- Updated tests to include new package references and ensure compatibility with changes.
