runner: bind-mount host kubectl into job containers; registry domain → neuralplatform.ai

gitea-runner: add container.options to mount /usr/local/bin/kubectl:ro
from the Legion host into every act_runner job container. Eliminates
per-run curl download in CI workflows.

ingress: change registry ingress hostname from registry.nook.family to
registry.neuralplatform.ai. Matches the domain used in Neuron CI and
neuron.yaml image reference. DNS CNAME + tunnel route already added.
