Subject: [PATCH] Fix MB-hit path: poll scanner for backcover photo at disc
 insert prompt

If Cover Art Archive has no backcover, the scanner server (already running
since EAN prompt) is now also monitored at each disc insert prompt via
_input_or_scan. On photo upload, Vision-LLM starts in the background and
the photo is saved as backcover.jpg after ripping. Phone photo takes
priority over any CAA cover.
