Drop the gate that skipped the docker subset when no PR-built node image
is available. Fork PRs lack the quay secrets, so build-docker-image
succeeds with an empty output and the subset now falls back to
DEFAULT_NWAKU instead of being skipped.
Pin DEFAULT_NWAKU to wakuorg/nwaku:v0.38.1. The rolling :latest tag is a
daily upstream master build and currently fails to boot with
"updateAddressInENR: Public key does not correspond with given private
key", which would have made the subset permanently red on fork PRs.
s31 passes against v0.38.1 and against the PR-built image.
Echo the resolved peer image at the start of the test step. The job name
is left static so the check can still be made required.
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).
