Pull request overview
This pull request fixes deprecation warnings from dependencies by upgrading python-dateutil and replacing the pytz library with Python's standard library datetime.UTC. The changes address warnings about datetime.datetime.utcfromtimestamp() being deprecated in favor of timezone-aware datetime objects.
Changes:
- Upgraded python-dateutil from 2.8.2 to 2.9.0.post0 to fix dateutil deprecation warnings
- Removed pytz dependency and replaced all usages with datetime.UTC (Python 3.11+ standard library)
- Updated uv.lock with dependency upgrades including django-tastypie, factory-boy, faker, model-bakery, and other transitive dependencies

Description
There's lots of deprecation warnings at https://github.com/python/pythondotorg/actions/runs/22328504402/job/64605126832#step:9:13
Most are from Django, but these are from dependencies:
The first is from dateutil. We can fix by upgrading to the latest version.
The second is from pytz. We only use
pytz.UTCfrom here, and can instead replace it with the stdlib'sdatetime.UTC, and ditch the dependency altogether.And run
uv lockto updateuv.lock.
