fix(recorders): queue proxy on finalize + custom clip names

- POST /api/v1/assets: when transitioning from 'live' to 'processing'
  with a hi-res key but no proxy, queue a proxy job instead of just
  flipping status='ready'. Recorder-captured clips now get a proxy
  + thumbnail like upload-path assets do
- POST /api/v1/recorders/:id/start now accepts { clipName } in the body;
  operator-supplied name (sanitized to [A-Za-z0-9 ._-], capped at 80)
  overrides the auto-generated <recorder>_<timestamp> fallback
- RecorderRow gets a 'Clip name (optional)' input visible when stopped;
  Enter triggers Record, value sent on POST start, cleared on stop
- New POST /api/v1/assets/:id/generate-proxy and
  POST /api/v1/assets/backfill-proxies for one-shot cleanup of pre-fix
  clips that have a hi-res master but no proxy
