Piece C of ADR 0056: an internal authority certifies routed names by the same
path a public one would, with the proxy pointed at whichever issuer the mesh
names and trusting that issuer's root.
step-ca (new): provides acme-ca (mesh scope), listens 9000 from mesh, persists
its CA home under uid 1000. The root CA cert reaches consumers as a served
value settled from a per-mesh operator setting (no baked root); the init
password and root key are sealed secrets, not literals. No route-name -> IP
hosts map (that is Piece B). Upstream smallstep/step-ca pinned by Docker Hub
digest.
route-proxy: requires + binds acme-ca. ACME_DIRECTORY is composed on the
consumer side from ${bound:acme-ca:at}:${bound:acme-ca:port}, and ACME_CA_BUNDLE
is a file whose content is ${bound:acme-ca:root} -- both from the binding,
replacing the hardcoded directory and the baked root PEM.
