fix(thermal): bump TTL 3h->6h and maxStaleMin 240->360 to stop 503 flapping (#2263)

Browse Source 
Root cause: thermalEscalation cron runs every 2h but CACHE_TTL was 3h (1.5x).
Any Railway delay caused the key to expire before the next run, triggering
EMPTY -> CRIT -> 503. Confirmed via health:last-failure Redis snapshot:
  thermalEscalation:EMPTY(183min) at 2026-03-26T00:04:17Z (and 04:04, 06:03)

- seed-thermal-escalation.mjs: TTL 3h -> 6h (3x the 2h cron interval)
- health.js: maxStaleMin 240 -> 360 (3x interval, consistent with pattern)
