Add unit tests and Gitea CI workflow for bug fixes

- Add fetcher/tests/ with 21 tests covering all bug fixes:
  - test_utils: get_with_protocol URL normalization (5 tests)
  - test_config: scheduled_tasks.json PK uniqueness, Celery queue
    settings (7 tests)
  - test_publish: URL routing and view for /task/publish_<id>/ (4 tests)
  - test_template_field: url_detail.html renders images_url field (2 tests)
  - test_search_postprocess: URL host filtering and param stripping (3 tests)
- Replace empty fetcher/tests.py with tests/ package
- Add .gitea/workflows/test.yml: runs on PRs and pushes to main,
  installs dependencies and runs `manage.py test fetcher.tests`
