Add logic to initialize at least one user if the startup wizard is not completed, both during application startup and in the startup user API. After user creation, reload the user entity with all related navigation properties to ensure the in-memory user object is fully populated. Also update build and publish metadata files.
Integrated Jellyfin.CodeAnalysis as a project reference across core and test projects. Added centrally managed code analysis and style enforcement packages (IDisposableAnalyzers, Microsoft.CodeAnalysis.BannedApiAnalyzers, SerilogAnalyzer, SmartAnalyzers.MultithreadingAnalyzer, StyleCop.Analyzers) to all affected projects. Updated dependency graphs, asset files, and build scripts to ensure analyzers run during builds, enforcing consistent code quality and style rules throughout the codebase. Removed custom warning properties to rely on analyzer enforcement.
- 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.
