fix: address PR #8019 review feedback

- Remove unused 'time' import from node:console in checkpoints/index.ts
- Fix CheckpointWarning component to preserve i18n link structure using Trans
- Add comprehensive test coverage for checkpoint timeout behavior (6 new tests)
  - 5-second warning message
  - Timeout error message
  - Warning cleared on success
  - Constant validation
  - Timeout conversion
  - i18n key verification

All 25 checkpoint tests passing.
