Replaces the placeholder bookmark links with real docker/database
widgets for every container in the 10 Projekte/stacks compose files
(traefik, coolify+redis+db, gitea+runner+db, code, immich+ml+redis+db,
n8n+db, passbolt+db, umami+db, headscale, mailpit) - the actual
"widgets for all services in Projekte/stacks" deliverable, not just an
example. Also turns on label-based discovery against falcon_network as
a safety net for anything added later without a config.yml update;
manual widgets here still take precedence for anything already listed.
Verified the config validates and renders with no schema errors, and
that a widget pointed at a container that doesn't exist in this
environment fails gracefully (a clean error result over the socket)
rather than crashing - expected here since none of the real stacks run
in this sandbox; wiring against the live falcon_network happens at
actual deploy time.
