…alth checks Add collectRpcHealthMetrics, which reuses rpc_poller_client's existing withRetry exponential backoff helper to retry transient RPC connection timeouts when fetching the latest ledger, instead of a bespoke retry loop. Failures that exhaust retries are recorded on the shared failure monitor as `rpc_timeout` so they surface through the existing threshold alerting. Closes Goldii-locks#334
