Remove unnecessary collectstatic step from CI test workflow

[Raghaddahi]

Relates to #406

Description

The CI test workflow was running collectstatic before tests, but this is unnecessary because the test settings (apps/guide/settings/test.py) already use CompressedStaticFilesStorage, which serves static files directly from app directories without requiring them to be collected into STATIC_ROOT.

The collectstatic command was doing nothing useful for the test run. The only static-file-related requirement for tests is that manifest.json exists (for manifest_loader), which is already handled separately in the workflow.

Changes

• Removed poetry run python manage.py collectstatic --noinput --clear from the CI test job

Testing

• Ran make test locally with DJANGO_SETTINGS_MODULE=apps.guide.settings.test
• All 48 tests pass
• No lint errors in changed files
