fix: expose helper functions at module level for test patching

- Move get_all_settings_from_db import to module level in app/views/settings.py
- Move get_provider_status and get_settings_for_display imports to module level in app/views/status.py
- Fix CI workflow: replace deprecated 'file' parameter with 'files' in codecov-action
- Fix CI workflow: update test results upload to use codecov-action@v5 with report_type instead of deprecated test-results-action@v1
