feat(catalog): wire up brand-first OEM catalog UI
- Add brand-catalog.js overlay: Brands -> Categories -> Parts flow - Update catalog.html: 'Por Marca' button opens BrandCatalog overlay - Optimize /vehicle-brands to query brands table (fast) instead of 256M part_vehicle_preview - Keep /brand-categories and /brand-parts using exact match on part_vehicle_preview - Integrate addToCart with existing CatalogApp cart
