feat(07-unified-service-catalog): rewire /admin/catalog CRUD + query layer to services table

- Task 1: Update getAllServices() and activeServices queries to read from services table instead of service_catalog
  - Both ClientFullDetail and ProjectFullDetail now return Service[] (not ServiceCatalog[])
  - Quote items label join remains unchanged — still references service_catalog for historical quote_items.service_id FK integrity

- Task 2: Rewire /admin/catalog actions and components to operate on services table
  - src/app/admin/catalog/actions.ts: createService/updateService/toggleServiceActive now write to services with optional category field
  - ServiceTable.tsx: Updated to Service[] type, added category column rendering
  - ServiceForm.tsx: Added optional category input field
  - QuoteTab.tsx: Updated activeServices type annotation to Service[]

- New services created via /admin/catalog have migrated_from=null, migrated_id=null (not migrated)
- TypeScript compiles successfully
- npm run build: PASS
