Check time-dependent tests on CI worker

Running these tests locally in a timezone well ahead of UTC gives:

And the output from CI is:

date.today()=datetime.date(2024, 4, 22)
date command: Mon Apr 22 23:43:14 UTC 2024

sample_to_insert=SampleUpsertInternal(id=None, external_id='EX_ID', meta={}, project=None, type=None, participant_id=None, active=None, sequencing_groups=[SequencingGroupUpsertInternal(id=None, type='genome', technology='short-read', platform='ILLUMINA', meta={'meta-key': 'meta-value'}, sample_id=None, external_ids={}, assays=[AssayUpsertInternal(id=None, type='sequencing', external_ids={}, sample_id=None, meta={'sequencing_type': 'genome', 'sequencing_platform': 'short-read', 'sequencing_technology': 'illumina'})])], non_sequencing_assays=None)
bad: today_bad=datetime.date(2024, 4, 22) type(today_bad)=<class 'datetime.date'>
good: today=datetime.date(2024, 4, 22) type(today)=<class 'datetime.date'>

This largely confirms the theory that tests never failed like this in CI because the workers run in UTC, so there is never this yesterday confusion.
