tautulli: its config is placed, it runs the build in use, and its runtime finds its own key

The module stated /services/tautulli/config and /var/lib/mesh/tautulli/route.json,
novox's layout, which no definition may carry (ADR 0112). Tautulli's config dir is
now a placed directory (${dir:config}) and the route binds into the placed state
(${dir:state}), as searxng and mosquitto do.

The image was pinned to v2.18.1-ls242; ace runs ls244 (2026-09-11), and Tautulli
migrates its own database schema, so the pin moves to the digest ace runs.

The runtime called http://127.0.0.1:8181, which is the software's port, not the
machine port the mesh assigns; it now asks with ${port:8181}, as gitea does.

The runtime mounted Tautulli's config dir read-only but never read it: its API key
could only come from MESH_TAUTULLI_APIKEY or the settings-merged config.json, i.e.
a secret in settings. Tautulli mints and owns that key in its config.ini, so the
runtime now reads it from there. Nothing for the mesh to mint or accept.

Verified: catalogue tests with MESH_CATALOGUE pointing here (not skipped); the
pinned image started in a throwaway container on a dir owned 1001:2000 with
PUID/PGID 1000 answers /status 200 and re-owns /config to 1000:1000 on start;
client.ts, run under node, read the key from that instance's config.ini and got
success from get_activity and get_history; without a config.ini it throws, which
the tools and events entrypoints already treat as "not configured".
