- Add master catalog (bambuLabCatalog.ts) as single source of truth for materials, finishes, colors, and refill/spool availability - Fix incorrect finish-per-material mappings (remove PLA: 85A/90A/95A HF/FR/GF/HF, add ASA: Basic/CF/Aero, fix PETG/PC) - Implement cascading filters on public site: material restricts finish, finish restricts color - Add AdminSidebar component across all admin pages - Redirect /upadaj to /dashboard when already authenticated - Update color hex mappings and tests to match official Bambu Lab names
