Reconcile FurnitureData.json with items_base after import

After every single import, batch import and batch-regen, cross-check all
items_base rows against the local FurnitureData.json: entries whose
spriteId drifted are corrected to the DB id, and missing entries plus
real id conflicts are reported in the API/SSE response. Entries that are
missing entirely are counted (rebuilding them needs SWF/nitro metadata).
