Root cause: switch-traffic.sh was modifying Traefik config in the CI checkout
directory ($GITHUB_WORKSPACE) instead of the deployment directory ($DEPLOY_PATH).
Additionally, the sed patterns didn't work with multi-line YAML structure.

Changes:
- Add DEPLOY_PATH environment variable support to all CI scripts
- Add --force-recreate flag to ensure containers are recreated with new images
- Fix weight update to use awk for reliable multi-line YAML editing
- Add scripts/ directory to rsync so SREs can run scripts from /opt/motovaultpro
- Add image verification step to confirm containers use expected images
- Add weight verification to confirm Traefik routing was updated
- Add routing validation step to verify traffic switch succeeded
