fix: correct CI format check and dart:format task ordering

- Add --output=none to dart format CI check so it doesn't modify
  files (--set-exit-if-changed alone still writes)
- Remove mise fmt --check from CI: mise is not installed in the CI
  environment (setup-flutter-app uses subosito/flutter-action directly)
- Make dart:format depend on generate so mock files are formatted
  after codegen, not before
