ci: install SSH client in Alpine Linux for deployment

Fix CI failure caused by missing SSH client in node:20-alpine image.

Problem:
- Alpine Linux doesn't include SSH client by default
- This caused CI to fail with '/bin/sh: ssh: not found'

Solution:
- Install openssh-client and rsync packages using apk
- This enables SSH connections to production server

This should resolve the final CI failure and allow successful deployment.
