CI: Docker build/push actions incompatible with Forgejo runner

Symptom

The ci.yml workflow uses docker/setup-buildx-action@v3, docker/build-push-action@v5, and docker/metadata-action@v5 which have compatibility issues with Forgejo's act_runner. The build step fails because Docker-in-Docker is not properly set up.

Context

The runner connects to Podman via docker_host: "tcp://127.0.0.1:12345" (proxy)
Third-party Docker actions expect direct Docker socket access
The runner's base container has no Docker daemon inside it

Suggested fix

Replace GitHub Docker actions with native docker build / docker push CLI commands in the workflow. For example:

- name: Build and push
  run: |
    docker build -t myapp:${{ github.sha }} .
    # Add docker push if registry configured

This repo already uses https://git.forgejo.org/actions/checkout@v4 (Forgejo-native) for checkout, which is good practice.
