Change nightly status script to not depend on time

[a-maurice]

Description

Provide details of the change, and generalize the change in the PR title above.

The nightly report routinely fails to find source tests because it is relying on the time, which is inconsistent. Instead, check if the run was invoked via a schedule, and the determine if it is Firestore by using the time.

Code Review

This pull request modifies the build status reporting script to select either the earliest or latest scheduled test run for a given day, removing the previous specific hour constraints. The reviewer identified critical issues in this new logic, including a logical bug in the date comparison (since comparing .date() objects on the same day will always evaluate to equal), unreachable code for non-Firestore runs, and suboptimal filtering order. A code suggestion was provided to resolve these issues by reordering the filters and comparing full datetime objects.
