fix: use PR number instead of ref_name for Docker image tags
GitHub's github.ref_name returns "421/merge" for PR merge refs, creating invalid Docker tags like "pr-421/merge". Docker tags cannot contain forward slashes. Changed to use github.event.pull_request.number which returns just the PR number (e.g., "421") for valid tags like "pr-421". Also added comprehensive unit tests for backup_service.go to meet the 85% coverage threshold. Fixes CI/CD failure in PR #421.
