Jinwoo Hong 79d5fb469a fix(cloud): recalibrate the relay monitor's postgres-retry freeze to a measured bar (#18580)
The global relay_cells FOR UPDATE lock made successful retries a
steady-state rate: fleet-wide p50 430 / p90 924 / p99 1320 / max 1504
per five minutes over the last 24 h, 55% of windows over the 300 bar,
only 22% of 15-minute gates clean. Three read-only dry-runs on
2026-09-04 froze on it, blocking the same-cap roll that carries #18521
and the beginProof crash guard to the 23 cells. 2000 clears every
measured healthy gate; the exhausted-retry, director concurrency, and
pool bars keep the incident discriminator role.
