jochen 13b7562c47 Keep secrets off command lines the runtime records (hq issue 282)
mesh/merge-gate pass: builds docker, keycloak, minio, mosquitto → ace, g14, novox, shanks; no bus step; 2 wait(s) for a person; every machine composes with…
mesh/repo-check pass: its merge-check.sh passed
mesh/delivery delivered
mosquitto passed the broker's admin password to mosquitto_ctrl as -P on
every docker exec, and the container runtime keeps every exec's command
line in its event stream, where docker_events returned it. The admin
credentials now reach mosquitto_ctrl as a 0600 options file fed on
stdin, client passwords at its own prompt, and an argv carrying a secret
is refused before it runs. The admin secret says it is taken at start:
the bootstrap re-runs when the mesh replaces it and re-keys the broker
online from the value it last applied, so it can be rotated.

docker_events redacts what an exec's command line carried, and
docker_secrets_in_events names such secrets by name. keycloak's repair
hands kcadm its passwords through KC_CLI_PASSWORD; minio gives mc its
root alias through MC_HOST_mesh.

jochen 69f2efb591 mosquitto: run mosquitto_ctrl inside the broker's container
The module's code moved out of its container and took mosquitto_ctrl from a host package. A
machine whose package index is stale cannot install it (hq issue 205), so the tools failed. The
broker's own image carries the tool at the broker's version: the tools exec into the running
broker, and the bootstrap seeds from a throwaway container of the same image.

jschoubben 1080f45012 mosquitto: a consumer's grant is the topics it asks for, and its binding says the port
mqtt-topic served nothing: with two listens the mesh could not say which port a consumer dials, so a
consumer had to type 1883 into its config. It now serves the MQTT listener's port (the machine's,
once assigned) and the scheme, so `${bound:mqtt-topic:port}` fills.

The provisioner confined every consumer to `<as>/#`, which leaves nothing for the consumers the
broker exists for: Home Assistant discovers under homeassistant/# and tasmota/discovery/#, and
Node-RED's flows follow the devices' own topics. A consumer now contributes `topics` (MQTT topic
filters) to its mqtt-topic requirement and is granted exactly those; with none, its own subtree as
before. Settings merge into contributions, so an operator narrows a grant per assignment. The role
is brought to exactly the wanted ACLs (stale ones removed), `holds` checks the ACLs too, and an
invalid list is refused, never quietly narrowed. Only the role named for the consumer is touched:
a client carried from the predecessor's password file keeps its own.
