docs(zonos-gateway): vh/zonos-gateway stood up in gitea (resolve not-in-gitea flag)

Created private vh/zonos-gateway on gitea, imported the previously-unversioned
~/zonos-gateway working tree (source + dials-first spec + voices). Updated the
stack README, spec §8, and the sister-repos table to point at the repo. Remaining
follow-up: CI + deploy key to wire the irv-ml1 deploy tree to the repo.
