fix: add polling timeouts and safe fallback in recovery script (#644)

Browse source 
- Add max-iterations guard (60 polls × 5s = 5 min) to both cooldown
  polling loops with explicit error on timeout
- Use LAST_RECENTER (already validated) as fallback instead of "0" for
  post-seed-buy lastRecenterTime read, preventing silent cooldown skip
  on transient RPC failure
