feat(scripts): add GitLab cleanup and redeploy utility

Add script to cleanly remove and redeploy GitLab:

redeploy-gitlab.sh:
- Deletes existing GitLab deployment and resources
- Removes associated PVCs and data
- Reapplies GitLab manifests from scratch
- Useful for recovering from misconfiguration
- Displays new root password after deployment

Note: Repository now uses Gitea instead of GitLab, but this
script remains for reference or alternative deployments.
