Robustness: crash-safe migrations, stale-run sweep, optional prep tools; branded 404

Browse Source 
- init_db applies each schema file with executescript (semicolons in triggers
  and string literals no longer break it) and records schema_version itself
  after each file, so a forgotten in-file bump can't re-run an ALTER and crash
  startup. Re-running is a no-op.
- On startup, sweep any job_runs left in 'running' (killed by a restart) to
  'interrupted' so the UI/history don't show a run stuck running forever.
- prep-audio.sh skips loudgain and cue_file cleanly when they aren't installed
  (they aren't in the base image) instead of failing on a missing binary and
  logging errors; pipeline-status.sh routes syslog through a guard so a missing
  `logger` doesn't spew into the job log.
- Add a branded 404 page (rendered to static HTML, no external runtime) via a
  custom exception handler that leaves all other responses, including the login
  redirect, untouched.
