Removed all references to the Jellyfin.CodeAnalysis project and related analyzer NuGet packages (IDisposableAnalyzers, SerilogAnalyzer, SmartAnalyzers.MultithreadingAnalyzer, StyleCop.Analyzers, Microsoft.CodeAnalysis.BannedApiAnalyzers) from test projects and their dependency graphs. Updated .dgspec.json, project.assets.json, and project.nuget.cache files accordingly. Also updated warningProperties to explicitly set warning behaviors. This streamlines the dependency tree and removes static analysis tooling from the test build process.
- 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.
