feat: auto-repair sprite_id drift after every import

The emulator sends items_base.sprite_id to the client and Nitro resolves
the furniture by looking up that id in FurnitureData.json. Legacy rows
where sprite_id drifted from the id made the client render a completely
different item (e.g. a wired or custom asset instead of the purchased
furniture).

Add verifyAndFixSpriteIds() which repairs any row whose sprite_id no
longer matches its id while the local furnidata carries the item under
that id, and run it after every import path (single, batch, batch-regen,
clone) next to the offer_id rebuild.
