fix: shopping list accuracy, Bring! cleanup server-side, vacuum prompt, recipe appliances

## v1.7.5

### Added
- Vacuum sealed prompt after item use (conf/weighted units, auto-dismiss 8s)
- Multi-function appliance awareness in Gemini recipe prompts (Cookeo/Bimby/Thermomix)
- Server-side Bring! cleanup in cron (no client page load required)
- shopping_name field in inventory_list API response

### Fixed
- Bring! cleanup: false token match (Succo/Frutta from product name tokens)
- Bring! cleanup: expired item with fresh family stock no longer flagged critical (Verdure)
- Bring! remove: catalog items now removed via German key fallback (Formaggio→Käse)
- Shopping list: isExpiringSoon false positives (requires pctLeft < 50%)
- Shopping list: expired batch suppressed when fresh restock >= 50%
- Cross-device cleanup: detect app-added items via spec markers not localStorage
- API fetch: cache: 'no-store' on all api() calls
- Shopping page: 45s polling for multi-client sync
