Roll out the tool runtime to the remaining tools+events modules (ADR 0052/0051)

Nineteen modules gain a broker-bound runtime container that serves the module's
tools under its own scoped account: bazarr, gitea, grafana, home-assistant,
icecast, influxdb, jackett, keycloak, mailu, nextcloud, nodered, nzbget, ombi,
photos, portainer, qbittorrent, searxng, tautulli, verdaccio.

Config is the assignment's, not the manifest's (ADR 0051): each client's fromEnv
overlays a settings-merged config file (MESH_<M>_CONFIG_FILE) over its env
fallbacks, so URL and credentials come from `settings set`, with the URL defaulting
to the server on the node. nextcloud and mailu also mount the docker socket for
their exec-based tools.

Proven in the mesh-lab: assigned-grafana green — settings deliver the URL and token,
the runtime reads the merged config and serves grafana's tools under the scoped
account, with nothing in the manifest. Two gaps this surfaced are filed as hq
issues 008 (a provider runtime's seal key) and 009 (a settings change does not
restart a container runtime).
