fix: update frontend workflows to use short SHA for image tagging

- Add short_sha generation and output to build jobs
- Update deploy scripts to use short SHA instead of full SHA
- Change env var names to FRONTEND_LEARNER_TAG and FRONTEND_MGMT_TAG
- Matches backend workflow implementation for consistency
