Delete Job

Purge a job’s content artifacts (result, input file, rendered pages).

The job’s metadata (existence, state, timings) stays queryable at /jobs/{job_id}; its result endpoint answers 410 afterwards. A job that is still running is cancelled first and recorded as failed, so the resume scan will not re-run it. Idempotent: deleting an already-purged job is a 204 no-op.

Works with or without a configured result_ttl_s.
