fix: harden furni import pipeline for production

- importSingleFurni: actually update an existing item instead of failing on a primary key INSERT collision; refuse to reassign a spriteId owned by a different classname
- reconcileFurniDataWithItemsBase: also sync each entry's offerid to the DB sprite id, not just the id
- Move the full-table interaction_modes_count verification out of the per-item import hot path and run it once per batch/single import
- clone-import: apply the auto-detected interaction_type (was hardcoded 'default'), set FurnitureData offerid and catalog_items.offer_id to the new local sprite id (was the source hotel's id / -1)
- clone batch route: run the same post-import reconcile/verify/ownership/RCON consolidation as the furni batch route
- upload-import: set offer_id to the allocated id in both the direct insert and the generated SQL migration (was -1)
- generateCatalogSql: use the classname as catalog_name and the item id as offer_id so rows match the app-managed import convention
- stats + missing-nitro endpoints: match catalog membership via item_ids instead of the catalog_name join, so translated display names no longer break counts
- deleteImportedItem/rollback: delete catalog rows by the canonical item_ids link only
- classifyFurni: wall items always classify as 'walls' before prefix rules (rare_/val_/xmas_) can misfile them
