Add image build support for component deployment

[vrubezhny]

Enables the deploy command to build container images as part of
the deployment flow. Uses podman, docker, or buildah in the
OpenShift terminal so users can interact with registry auth prompts.

Key changes:

• ContainerRuntimeDetector: Detects available runtime (podman > docker > buildah)
• ApplyCommandExecutor: Builds image components in terminal instead of skipping
• Unit tests: ContainerRuntimeDetector, image build logic, manifest URI handling,
  deploy state loading
• Integration tests: Runtime detection, deploy/undeploy with inlined resources,
  local image build without registry
