fix(ui): playlist search with artist+title, artist in missing list, no bounce on job cards

- Playlist track search: use 'Artist Title' query + songCount=10 (was title-only + 5)
  fixes songs like 'Dead' by Geoxor being missed due to common-word collision
- Missing tracks now show 'Artist – Title' instead of just title
- renderJobs: update existing cards instead of full innerHTML wipe every 1.5s
  eliminates slideUp animation re-triggering on every poll tick
