feat: add Loyalty+ platform with pages (Phase 6)
- Add alembic migration for Loyalty platform (z5f6g7h8i9j0)
- Insert platform: code='loyalty', domain='loyalty.lu', path_prefix='loyalty'
- Create platform marketing pages: home, pricing, features, how-it-works
- Create vendor default pages: about, rewards-catalog, terms, privacy
- Update implementation plan to mark Phase 6 complete
Platform routing handled automatically by PlatformContextMiddleware
via path_prefix detection for /loyalty/* URLs.
