fix: add compose-workflow checkout for deployment scripts

The deploy workflow was failing because deployment scripts were not available
on the runner. Added checkout step for compose-workflow repository to make
scripts/deployment/ available.

Issue:
- docker-piwine-office deployment failed with "No such file or directory"
- Error: ./scripts/deployment/lib/ssh-helpers.sh not found
- Target repository checkout doesn't include compose-workflow scripts

Solution:
- Added checkout step for owine/compose-workflow@main
- Checkout to .compose-workflow/ path
- Updated all script references to use .compose-workflow/ prefix:
  - ssh-helpers.sh (2 occurrences)
  - detect-removed-stacks.sh
  - deploy-stacks.sh
  - health-check.sh (2 occurrences)
  - rollback-stacks.sh

This mirrors the fix already applied to lint.yml in commit a6bf189.

Fixes: Run #20542794665 in docker-piwine-office
Validated: actionlint passes
