Ruben Fiszel e16061df06 fix(health): detect read-only replica via pg_is_in_recovery() (#9722)
The /api/health/status database check used `SELECT 1`, which succeeds
even on a read-only standby. After a PostgreSQL failover where the
primary becomes a secondary, the health check kept reporting healthy
while all writes failed with "cannot execute INSERT in a read-only
transaction", so Kubernetes liveness probes never restarted the pod.

Use `SELECT NOT pg_is_in_recovery()` instead: it returns true on a
primary and false on a standby, so a read-only replica is now reported
unhealthy. Result handling checks the returned bool (Ok(Some(true)))
rather than just query success.

Fixes WIN-2085
