fix(sxyprn): disable thumbnail refresh job — trafficdeposit token has ~1h TTL

Browse source 
CORRECTION: trafficdeposit thumbnail tokens are hour-bucketed and valid only ~1h
(verified 2026-06-10: stored ts=11:00 dead at 12:27, current ts=13:00 loads). Earlier
"~weekly rot" read was wrong. Storing/periodically-refreshing sxyprn thumbnail URLs
is futile — they expire within the hour. Default the refresh job OFF (kept in code).
The dead-marking sweep (Post Not Found → dead_at) it performed was still valid. Live
sxyprn thumbnails need on-demand resolution at serve time (future work).
