Pratik Mankawde ec308c6b00 fix(telemetry): poll the parity queries instead of racing one instant query ...

The four external-parity bounds checks each ran a single Prometheus instant query
and failed on an empty result. The metric checks that run earlier poll
/api/v1/series, which returns a series regardless of staleness, but a bounds
check needs the sample value and so cannot use that endpoint. This file's own
docstring records the consequence: a beast::insight gauge that stops changing can
fall out of an instant query while /api/v1/series still returns it, so one
attempt is not enough to call the series absent.

Poll to the same deadline the metric checks use. A Prometheus error is raised
rather than retried, because a rejected query never becomes valid and retrying it
only burns the full timeout.
