Link retail POS products to the CRM products API (restaurant stays local)

Products are now mode-aware:
- Retail: the catalog lives in Ladill CRM. The Products page proxies CRUD to the
  CRM products API (CrmClient gains product/create/update/delete), and the
  register reads CRM products live; a sold line is stored as a name/price
  snapshot (product_id null, since CRM products aren't local rows). Resilient —
  the register shows an empty catalog if CRM is unreachable. CRM import is hidden
  in Settings (not needed when reading live).
- Restaurant: unchanged — the local pos_products catalog keeps its POS-only depth
  (category, kitchen station, course, modifier groups).

ProductController routes take a raw {product} id (CRM id in retail, local id in
restaurant). Suite green (17), covering both modes.
