Surface silent exceptions in workers + repair jobs — ~30 sites

Across all background workers (Spotify/Tidal/Deezer/Qobuz/iTunes/
Discogs/Genius/AudioDB/MusicBrainz/Last.fm/SoulID + the metadata-update
worker) and the repair-job scanners. All converted to
`logger.debug("...: %s", e)`.

Two `_e` renames in genius_worker and soulid_worker where outer scope
was already binding `e`. Two finally-block sites in repair_jobs/
library_reorganize.py left silent (conn.close on shutdown path).
