Fix GitLab CI: disable all template jobs on production branch and enable rsync
Changes:
- Fixed rsync trigger to run on "production" branch (not main/master/prod)
- Added overrides for ALL template jobs to prevent them from running on production branch
- Jobs disabled: prepare, setup:volumes, setup:volumes:check, deploy, deploy:production, verify, verify:deployment, cleanup, cleanup:registry, cleanup:registry:aggressive, rollback, rollback:production
- Now only the custom rsync:prod job will run when merging to production
