umami: the reference module — a provider as well as a consumer

umami was only half a module: it required postgres but did not provide
what it exists to offer. It now provides the mesh 'analytics' interface
(ADR 0045) — a webapp requires analytics and umami's provisioner creates
its site and returns the grant — mirroring the postgres provider pattern
(serves/receives/grants + a provisioner container that adapts umami's API
to the mesh contract).

Also: split the listen (one port, two surfaces — the mesh-gated dashboard
and the public collection endpoint browsers POST to, hence from:anywhere),
and an admin own-secret for the provisioner to drive umami's API.

Parses against internal/catalogue. Still to build: the provisioner image
(mesh-provision-umami-analytics — the adapter, real code like
postgres-provisioner; placeholder digest for now) and umami's tools/client
in the module (ADR 0044), which need the sdk harness.
