chore: fix django flaky tests as of Feb 2025

[wantsui]

Many of the Django tests were marked with expired flaky time stamps.
This PR attempts to fix that.

Tests:

• test_cached_template - I extended the flaky timestamp unless I think of an easy way to force the Django view to cache twice consistently. Weirdly enough, it only flakes when the entire CI runs but not if you run this specific test individually.
• test_psycopg3_query_default - For some reason, this test fails sometimes because the pq module is not available. I'm currently waiting for the CI to run all the variations to see if this works.
• test_urlpatterns_include - fixed incorrect service name
• test_cached_template - fixed incorrect service name
