"""mattermost-lts — Q4.5 recipe-specific functional test (plan §4.3: "create the app's primary
object — a message — and read it back").
Exercises mattermost's core function end-to-end against the live per-run deploy, via the REST API:
1. Bootstrap the FIRST user (a fresh mattermost server lets the first user be created unauthenticated
and makes them system admin).
2. Log in → capture the session token from the `Token` response header.
3. Create a team, then an open channel in it.
4. POST a message (a unique marker) to the channel.
5. GET the post back by id and assert the message text round-trips intact.
NOT health-only: a mattermost whose DB/API/posting path is broken fails here even though `/` and
`/api/v4/system/ping` return 200. The marker is unique per run so a stale/echoed response can't pass.
