perf(metrics): ask Sentinel to bucket metric history rows

Send bucket_ms on the Sentinel metric history reads so Sentinel averages
the rows and sends far fewer of them over SSH. Older Sentinels ignore the
param and return raw rows, which Coolify still buckets and downsamples.

Also quote the history URL in the single-fetch curl command, because the
URL now has an & in it.
