fix(shopping): prevent cleanup from removing user-manually-added items

- cleanupObsoleteBringItems now protects items the user explicitly added
  from the suggestions panel via a '_userPinnedBring' localStorage set
  (30-day TTL, cleared on force-sync)
- cleanup now protects ALL smart-predicted items (any urgency), not only
  critical/high — if the algorithm still flags it, it should stay in list
- autoAddCriticalItems: bypass purchased-blocklist for depleted items
  (current_qty=0) so products that ran out are always re-added to Bring
- forceSyncBring also clears _userPinnedBring for a full reset
