feat: service offer tags, catalog cleanup, offer editor filter

- Import 58 offer membership tags for all 55 services (entity_type="services")
  via scripts/import-service-offer-tags.ts (already run on prod)
- ServiceTable: remove Categoria column, rename Tag → Offerta; QuickAddRow
  no longer has a category field (offer tags set post-creation)
- offer-queries: getOfferEditorData fetches offerTags per service (join on
  tags WHERE entity_type="services") and exposes them in OfferEditorData
- OfferEditorClient: filter chips above "Servizi Inclusi" — Tutti / Entry
  Offer / Signature Offer / Retainer Offer, derived from actual tag data
