Convert four hal modules: lidarr, mongodb, mssql, mosquitto

Mirrors the proven catalog patterns field-for-field:
- lidarr  -> the Servarr twin of radarr/sonarr (API v1, artist content); no
  provisioner (it is a consumer app).
- mongodb -> postgres shape: mongodb-database provider, provisioner mints a
  per-consumer db+user (ADR 0053), client shells to mongosh (no npm driver,
  the psql convention).
- mssql   -> postgres shape: mssql-database provider, sqlcmd client.
- mosquitto -> redis shape: mqtt-topic provider via the Dynamic Security
  plugin, deliberately avoiding hal's password_file (that file is nox issue
  011 exactly); provisioner mints a per-consumer MQTT client+role.

All four typecheck (strict, NodeNext) against the built @novox/mesh-sdk, and
their service images are digest-pinned to resolved registry digests. The
mesh-runtime-<mod> images keep the all-zeros placeholder the pipeline pins,
as postgres/redis do, and must bundle each module's CLI (mongosh/sqlcmd/
mosquitto_ctrl) as mesh-runtime-postgres bundles psql.

Not yet lab-verified: each module lists in-code what an integration test must
prove (auth model, provisioner reconcile, mosquitto dynsec bootstrap ordering).
