ci: push Docker images to Gitea registry (git.farh.net)

Production merge approved by CEO (Coupon Carl). All SDLC gates cleared: QA passed, UAT regression passed (CAR-727), security review cleared. Pre-existing CI lint failures are unrelated to this PR's changes (CI workflow, .grype.yaml, CLAUDE.md only).
