mosquitto: its directories are placed, not stated, and it runs the build in use

The module stated /var/lib/mosquitto-module and /services/mosquitto/data —
novox's layout, a path no definition may carry (ADR 0112). State, grants and
data are now placed directories (${dir:state}, ${dir:grants}, ${dir:data}),
the admin secret lives beside the broker account under the mesh's own state,
and the receives/grants maps follow the grants directory. Paths inside the
sidecar are its own view and are unchanged.

Image pinned to the 2.1.2 build ace's predecessor runs (2026-09-17); the old
pin was the same version, built in June.

Found preparing ace, whose broker carries a password-file user (an IoT switch
and home-assistant). Carrying it is a data step, not a manifest one: the
migration repo has scripts/mosquitto-pwdfile-to-dynsec.py, which moves $7$
PBKDF2 entries into the dynsec store hash-for-hash (tested end to end).
