Brand catalog now follows the same navigation as the regular catalog:
1. Brands -> 2. Models -> 3. Years -> 4. Engines -> 5. Categories -> 6. Parts
Backend:
- Add /mye-parts endpoint for MYE-specific parts with category filter
- Uses existing /models, /years, /engines, /categories endpoints
Frontend:
- Complete rewrite of brand-catalog.js with breadcrumb navigation
- State machine: brands -> models -> years -> engines -> categories -> parts
- Search and pagination preserved at parts level
- Breadcrumb allows jumping back to any previous step
- Add #brandCatalogSearch container in HTML for search inputs
- Move brand search input out of renderBrandList so it persists while typing
- Move parts search input out of renderPartsList so it persists while typing
- Reset now clears search container
- Bump JS cache bust to v=3
brand-catalog.js was missing Authorization header on fetch calls,
causing 401 Unauthorized errors. Now reads pos_token from localStorage
and includes Bearer token in every request. Also handles 401 responses
by redirecting to /pos/login. Bump JS cache bust to v=2.
Backend:
- Add 'search' param to /brand-parts endpoint (filters oem_part_number and name via ILIKE)
- Keep count query accurate with search filter
Frontend (brand-catalog.js):
- Brand search input: filters 619 brands locally while typing
- Parts pagination: Previous/Next buttons with page counter (50 per page)
- Parts search within category: search input + Enter key triggers backend search
- Visual polish: stock badges, empty-state messages, responsive layout
- Loading states and breadcrumbs improved
