chore(deploy): raise gunicorn thread pool to 32 for SSE headroom

Browse source 
Each SSE log-viewer or job-log stream holds a thread for its full
lifetime. With --threads 8, a handful of open browser tabs could
exhaust the pool. 32 keeps the same single-process scheduler invariant
(_claim_lock in job_worker is process-local) while giving SSE plenty
of headroom on the test box's user count.
