Parametrize e2e-api-tests.yml with `subset` (non-docker|docker) and `node_image` inputs, and add a send-api-e2e-docker-tests job that runs the docker_required wrapper tests (S19/S20/S31) against the built node image.
The docker job needs both the liblogosdelivery artifact and the container-image build, and skips when no image is available (fork PRs lack the registry secrets). The non-docker subset still needs only `build`, so a docker-image build failure cannot mask its result.
Migrate the liblogosdelivery API/wrapper pytest suite into tests-e2e/ and run it in CI (e2e-api-tests.yml) against the built library. Edge senders use the real lightpush path (relay=False).
