feat(setup): add done button and integrate NFO scan into initialization

- 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
