fix(ci): merge build-native and docker into one job to avoid 117MB artifact upload

The runner (runner-lxc-quarkus, using act) fails to upload the
117MB native binary via actions/upload-artifact@v4 with exit code 1
after 3 minutes. Avoid the artifact transfer entirely by collapsing
build-native and docker-native into a single job: build native
binary, then build the Docker image directly from the working tree
in the same container.

The container has the binary at target/shot-crafter-calculator-1.0.0-runner
and the Dockerfile expects it at the same path, so the build
chain works without any artifact download/upload.

Push only happens on push to main (not on PRs).
