Pratik Mankawde ebe54d9db5 fix(telemetry): correct two alert thresholds found by 7-day backtest ...

ValidatedLedgerStale fired on every node, healthy included.
LedgerMaster::getValidatedLedgerAge() returns weeks{2} (1209600s) as a
SENTINEL when no validated ledger exists, not as a measurement. The rule
read that as "14 days stale". Measured over six days it produced sustained
firing on all nine nodes. Excluding the exact sentinel value drops that to
zero while still tracking real staleness.

ManifestFloodInbound at 50 kB/s was routine paging: ~41 sustained 5-minute
samples across six healthy nodes in six days. Healthy p99 is 1.0-1.8 kB/s
and real storms peak at 2.7 MB/s, so 512 kB/s sits ~280x above normal and
~5x below the peaks, cutting sustained samples to 2.

Both thresholds were previously justified from a 24-hour window, which was
too short to expose either problem.
