fix(ci): remove GHA cache-from/cache-to (CAR-1357)

The build-and-push job fails post-merge of CAR-1356 REGISTRY_TOKEN fix:
cache-from/cache-to: type=gha backend does not exist on Gitea. Build
succeeds but post-build cache export fails and cascades to skipping the
Push Docker image step. Confirmed in uat run 3444 + dev run 3445.

Per CAR-1362, drop cache-from and cache-to from both Build and Push
Docker image steps. Matches proven-green cartsnitch/auth/ci.yml pattern.

Refs: CAR-1362, CAR-1356, CAR-1330, CAR-1357.
