feat(worker): Pass commit timestamp to test analytics status check

[sentry]

Fixes WORKER-VPM. The issue was that: get_test_status calls get_pr_comment_agg without lower_bound_timestamp, forcing unoptimized TimescaleDB query.

• Modified get_test_status to accept an optional lower_bound_timestamp parameter.
• Passed the new lower_bound_timestamp to get_pr_comment_agg for more precise test analytics aggregation.
• Updated notify_commit_comparison task to provide the commit's timestamp when checking test status.

Note

Low Risk
Low risk: a small signature change to get_test_status and its call site to add an optional timestamp filter, primarily impacting the Test Analytics aggregation query path.

Overview
Updates the worker’s Test Analytics status check to accept an optional lower_bound_timestamp and forwards it to get_pr_comment_agg to constrain the underlying aggregation query.

The notifications task now passes the commit’s timestamp when calling get_test_status, aiming to reduce query cost/noise while preserving existing pass/fail behavior.
