Vendor mapping: wildcard ignore patterns, bulk CSV import, multi-lot qty

- Add glob pattern support (* and ?) for ignore rules stored in
  qt_vendor_partnumber_seen (is_pattern flag, migration 041)
- Pattern matching applied in stock/competitor import, partnumber book
  snapshot, and vendor mappings list (Go-side via NormalizeKey)
- BulkUpsertMappings: replace N+1 loop with two batch SQL upserts,
  validating all lots in a single query (~1500 queries → 3-4)
- CSV import: multi-lot per PN via repeated rows, optional qty column
- CSV export: updated column format vendor;partnumber;lot_name;qty;description;ignore;notes
- UI: ignore patterns section with add/delete, import progress feedback
- Update bible-local/vendor-mapping.md with new CSV format
