chore: promote uat to production (Grype image vulnerability scanning)

Merges Grype-based container image vulnerability scanning and Docker CVE remediation to production.

- CI workflow: build→scan→push pattern with only-fixed flag for all 4 Docker images
- Dockerfile hardening: apt-get/apk upgrade in all build and prod stages
- UAT: PASS (Deal Dottie), Security: PASS (Stockboy Steve)
