fix(ci): unblock melos run analyze + test on fusion-app

- Add !context.mounted/!mounted guards in control_panel_screen and
  location_map to clear use_build_context_synchronously info-level
  lints that were failing flutter analyze
- Wrap PrimaryButton's Text in Flexible so TextOverflow.ellipsis
  can truncate when width is constrained (Row was overflowing 44px
  with the "small" golden scenario)
- Regenerate primary_button and secondary_button goldens after the
  layout fix
- Remove empty boilerplate widget_test.dart from
  flutter_treezor_entrust_sdk_bridge/example (referenced an SDK with
  platform channels that crashed in vm test mode)
- Gitignore **/test/failures/ (transient diff artifacts written by
  flutter test when goldens fail)

Also dropped 10 empty test/ directories scaffolded by flutter create
that were failing melos run test with "Test directory does not
contain any test files": auth, dashboard_shell, home, legacy_auth,
notifications, profile, sca_treezor, sf_infrastructure, splash, utils
