Users were incorrectly redirected to /login during the initial loading phase
before the loading was actually complete. Added loading_started and
loading_complete flags to properly track the initialization state so
the setup redirect middleware knows when it's safe to redirect.
- Add /api/setup/unresolved/done endpoint to mark phase complete
- NFO scan now runs after series sync during initialization
- Middleware redirects to /login after setup complete (was /loading)
- Done button allows skipping folder resolution with redirect to NFO scan phase
Added documentation for API, architecture, configuration, database,
development guide, testing, and navigation. Includes helper scripts,
diagrams, and guides for NFO files and migration.
