fix: furniture interaction detection and automatic catalog offer_id rebuild

Interaction detection:
- Trust SWF-derived sit/lay/stand flags only when the logic XML actually
  contains action data (new hasActions metadata); otherwise fall back to
  keyword detection so custom furni without <action> nodes are still
  classified correctly
- Add French/Dutch/German/Spanish/Italian keywords (chaise, banquette,
  stoel, silla, sedia, stuhl, tafel, mesa, ...) to sit/lay/stand detection
  with token-boundary matching to avoid false positives like bedside_table
- Unify interaction_modes_count priority: mechanic fixed modes, then raw
  animation state count, then sit/lay fallback, then keyword default
- Detect mechanic type even when real flags are not used

Catalog integrity:
- Skip duplicate catalog_items inserts in clone and upload imports
- Re-check live catalog rows before applying generated repair SQL
- Add rebuildCatalogOfferIds() which rebuilds every catalog_items.offer_id
  from the local FurnitureData.json (matched by entry id, then classname)
  and run it after every import path (single, batch, batch-regen, clone)
