Shopping links previously hardcoded to US storefronts. Users in other regions
got broken Amazon Fresh and Instacart links. Now locale is stored as a user
setting and passed to GroceryLinkBuilder at request time.
- locale_config.py: per-locale Amazon domain/dept config (already existed)
- grocery_links.py: GroceryLinkBuilder accepts locale=; routes Instacart to .ca
for Canada, uses amazon_domain per locale, Instacart/Walmart US/CA only
- settings.py: adds 'shopping_locale' to allowed settings keys
- shopping.py: reads locale from user's stored setting on all list/add/update paths
- SettingsView.vue: Shopping Region selector (NA, Europe, APAC, LATAM)
- stores/settings.ts: shoppingLocale reactive state, saves via settings API
Cloud mode: attach shared read-only corpus DB (RECIPE_DB_PATH env var)
as "corpus" schema so per-user SQLite DBs can access 3.19M recipes.
All corpus table references now use self._cp prefix ("corpus." in cloud,
"" in local). FTS5 pseudo-column kept unqualified per SQLite spec.
compose.cloud.yml: bind-mount /Library/Assets/kiwi/kiwi.db read-only.
Also fix batch of audit issues:
- #101: OCR approval used source="receipt_ocr" for inventory_items — use "receipt"
- #89/#100: Shopping confirm-purchase used source="shopping_list" — use "manual"
- #103: Frontend inventory filter sent ?status= but API expects ?item_status=
- #104: InventoryItemUpdate schema missing purchase_date field; store.py allowed set also missing it
- #105: Guest cookie Secure flag tied to CLOUD_MODE instead of X-Forwarded-Proto; broke HTTP direct-port access
