test(php): update existing tests for agenda model

- Fix uploaded_at in InformationBlockTest and ServiceControllerTest
  (Faker ignores Carbon::setTestNow, generating future dates that fail
  the uploaded_at <= service.date filter)
- Add agenda item association tests to ModerationBlockTest (3 new tests)
- Add agenda item association tests to SermonBlockTest (3 new tests)
- Verify legacy slides without agenda item still work

Test results: 12 failures (down from 14 baseline), all pre-existing
(ProPresenter parser path issues + suite ordering flake)
