fix: repair Rentman equipment sync with real API field mapping
- Map real Rentman fields: price -> rental_price, folder -> category/subcategory
(resolved via folder hierarchy to top-level categories), code -> number,
shop_description_long (fallback short/external_remark) -> description (HTML stripped)
- Sync only in_shop items; exclude archived/temporary from public catalog
- Extract known brands from equipment names (d&b, Shure, Pioneer, ...)
- Build specifications from physical fields (power, weight, dimensions)
- Persist equipment images in docker volume (survive redeploys)
- Router: filter available items, add price_asc/price_desc sorting
- Frontend: show prices in catalog card, detail page and cart with
per-day subtotal; price sorting options
- Tests: use real Rentman field names in fixtures, mock folder_map
