The rest of the catalogue becomes mesh-buildable (issue 060, batch 2)

The 21 media/home modules, the SaaS tool modules (cloudflare-dns,
confluence, gitlab, jira), model-usage, and the model-access trio get
the same Dockerfile + build section as batch 1. Scheduled-only modules
(anthropic-consumer, anthropic-manager, openai-consumer) deliberately
declare no MESH_TOOL_MODULES — every container of theirs names its
command. mosquitto's run-once bootstrap container builds from the same
artifact. Modules with third-party deps (model-usage: pg;
anthropic-manager: tweetnacl) install them beside their compiled code.

Also fixes cloudflare-dns's package.json, unparseable since its
description lost a closing quote.

Deliberately still without build sections: builder and mesh-controller
(the foundation builds them by its own path), distribution (provides
the artifact store — building it through itself is refused by design),
route-proxy (cross-repo build context, deferred), and the
upstream-image-only modules, which have no code to build.
