Backfill missing nitros into the Gamedata bundle on import

After each single import, batch import and batch-regen, copy every
.nitro file that is missing from /var/www/Gamedata/bundled/furniture so
the emulator can render all imported furniture even when the mirror write
was skipped. Reports the copied files in the API/SSE response.
