[6.16.z] Fix test_positive_global_registration_end_to_end flakiness

[Satellite-QE]

Cherrypick of PR: #21668

Problem Statement

The test_positive_global_registration_end_to_end test fails intermittently due to a date-boundary race condition.
The test asserts that today's date appears in yum history output, but when the test runs
near midnight in the content host's local timezone, the yum operations can complete just before midnight (e.g., 2026-05-14 23:59) while the assertion executes just after midnight (e.g., 2026-05-15 00:00:53).
This causes the date check to fail because datetime.now() returns the next day's date, which doesn't match any entry in yum history.

Solution

Accept either today's or yesterday's date in the yum history assertion, accounting for the possibility that operations span the midnight boundary in the content host's timezone.
