test(observability-metrics-aws-cloudwatch): fix time-rotted default-step test (#279)

* test(observability-metrics-aws-cloudwatch): fix time-rotted default-step test

TestGetResourceMetricsAppliesDefaultStep hardcoded a fixed start time
(2026-05-04) that flows into normalizeStandardMetricPeriod, which derives
the minimum period from time.Since(start) against the real wall clock.
Once the wall clock passed the 63-day retention threshold, the minimum
period was bumped from 300s to 3600s, breaking the "default step" assertion.

Use a time.Now()-relative start time so the query window stays recent,
matching the sibling tests (NormalizesSubMinuteStep, etc.) and keeping the
test focused on the behavior it asserts.
