## Changes
### Backend (vehicles.service.ts)
- Download ALL subgroup schema images on-demand (not just first)
- Store per-subgroup schemaWidth, schemaHeight, and hotspots in DB
- Return per-subgroup hotspot data in API response
### Frontend ([categoryId]/page.tsx)
- Add useMemo hooks for selectedSubGroupData, schemaImageUrl, hotspots
- Hotspots now properly update when subgroup changes
- Schema image changes correctly with subgroup selection
- Reset imageSize state on subgroup change for hotspot recalculation
### PL24 Integration
- Add pl24-db.service.ts for database operations
- Improve schema image downloading and caching
## Bug Fixed
When switching between subgroups (tabs) on the category parts page,
the schema image was changing but hotspots remained fixed on the
first subgroup's values. Now both image and hotspots update correctly.
