Add automatic PostgreSQL database creation and migration

- Added Jellyfin.Database.Providers.Postgres project with full EF Core migration support for PostgreSQL. - Implemented automatic database creation and privilege assignment on startup. - Generated initial migration and model snapshot for PostgreSQL schema. - Updated build, test, and dependency files to include PostgreSQL provider and Npgsql packages. - Added PowerShell script for generating and testing PostgreSQL migrations. - No changes to application logic outside database provider/migration infrastructure.
