A proof branch, not for main: the route-forwarding bed reads this module's literal
image and would break until the module is built.
The modelling is right regardless — the image is upstream, so the mesh should
mirror it once into its own registry and pin what that registry assigned, rather
than every machine fetching a reference somebody else can move.

Piece A + B of ADR 0056, completing the internal-CA work in ff01ada.
Selectable issuer. acme-ca is now a role two providers can satisfy: step-ca
(internal CA) or the new public-acme (a fact-only module, no container/listen)
that serves Let's Encrypt production. A mesh assigns one or the other to satisfy
route-proxy's `requires: acme-ca`.
One directory shape for both. A provider serves the ACME directory's parts the
way the mesh already models any reachable service -- an address (`at`), a `port`
and a `path` -- and route-proxy composes `https://<at>:<port><path>`. step-ca
lets the mesh fill `at` (its node) and `port` (its single listen) and serves only
`path`; public-acme, not being a mesh service, serves all three (overriding `at`
with the public host). Same composition either way.
Empty root means the system trust store. Both providers serve `root`: step-ca
the operator root PEM (settled per mesh), public-acme an empty string. route-proxy
writes it to the CA bundle file unconditionally; the binary now reads an empty
bundle as "the root is already trusted by the OS" and falls back to system roots
(examples/route-proxy/main.go, committed on the mesh-control ADR-0056 branch).
step-ca inits from the operator's root. The operator's root cert, root key and
root-key password are mounted at the smallstep entrypoint's default init paths
(/run/secrets/root_ca.crt, root_ca_key, root_ca_key_password) with the matching
DOCKER_STEPCA_INIT_*_FILE vars, so `step ca init` adopts the operator's root
instead of self-generating one -- the CA that signs is the CA route-proxy trusts.
Route names are labels, not FQDNs. Every routed module now contributes a `label`
(the leftmost subdomain) instead of a full public hostname; the node's public
domain composes the name. Apex (novox.be) is left as a full name -- composeName
has no empty-label/apex convention yet (mesh-control follow-up).

route-proxy is the shipping form of the reference reverse proxy (novox/hq
ADR 0007, 08-connectivity section 3): it provides route, is given every
consumer as the file at receives.route, and forwards by the Host header. It
ships the Go proxy from mesh-control/examples/route-proxy via a multi-stage
Dockerfile; no broker, own-secret or provisioner, since it only reads the file
the mesh writes.
ACME_DIRECTORY defaults to Let's Encrypt staging and is overridable per node to
production, so there is no hardcoded production default -- resolving novox/hq
04-ISSUES/004. hello-web is a minimal consumer that requires route and
contributes name+port, to exercise the grant.
