fix(tests): resolve 13 failing unit tests

- Use dynamic APP_VERSION instead of hardcoded v1.3.6 in:
  test_template_helpers, test_health, test_page_controller
- Add unresolved_folders to EXPECTED_TABLES in database/init.py
- Fix shallow copy bug in test_serie_scanner.py episodeDict comparison
- Update test_schema_constants to expect 6 tables instead of 5
