Backfill icons too in the Gamedata bundle sync

Extend the post-import backfill to also copy missing _icon.png files
into /var/www/Gamedata/icons (in addition to nitros into
bundled/furniture) so all imported furniture shows an icon in-game.
Report copied nitros and icons separately in the API/SSE responses.
