Claude 52b4606ab5 Add optional per-service companion doc files to write_readme
Any services/<name>.md next to services/<name>.sh gets appended to the
generated ~/docker/<name>/README.md automatically, with no changes needed
to the calling install_<name>() function. Keeps install-time-invariant
walkthroughs (third-party UI linking steps, multi-account setup) out of
the compose/README heredocs, which should stay focused on values chosen
during install.

Add services/traccar.md as the reference example: documents the
per-user Connections-tab linking needed for ntfy notifications to reach
non-admin accounts, and why TEST CHANNELS can return success without
actually sending anything (Traccar's SMS notificator silently no-ops
when the logged-in user's Phone field is empty).

## Getting ntfy notifications to actually fire (multi-user setup)
If `.env` has `SMS_HTTP_URL` set (the ntfy setup above), a Traccar user still
needs two separate things configured on their own account before they'll
receive anything — this trips people up because both are per-user, not
global, and neither is optional:
1. **Their own Phone field set to their ntfy topic.**
Settings → Users → click the user → Phone field → their topic name.
Different users can share one topic or each get their own, depending on
whether you want them to see the same alerts or separate ones.
2. **The notification rule linked to that user.**
Creating a notification (e.g. "Geofence exited" with the SMS channel
checked) does not automatically apply to every user — it has to be
attached. Go to **Settings → Users → click the user → Connections tab**,
and select which Devices, Geofences, Notifications, and Users are linked
to that account. A user only gets alerts for notifications, devices, and
geofences actually selected there.
Both steps are required per account. There's no way to configure this once
for everyone — a non-admin user who can't see a device/geofence/notification
in their own Connections list won't get notified about it, even if the admin
configured everything else correctly.
### Why "TEST CHANNELS" can return success with nothing arriving
The `TEST CHANNELS` button only ever tests the **currently logged-in
session's user** — there's no way for an admin to test "as" another account.
Worse, it can report success (HTTP 204) even when nothing was sent: Traccar's
SMS notificator silently no-ops (no error, no log line) if that user's Phone
field is empty, since `HttpSmsClient` — which is what actually calls out to
ntfy and would throw on failure — never gets invoked in that case. A 204
from this button only proves the request loop completed, not that ntfy was
reached.
To verify a specific account actually works, log in **as that account** and
click the button there, or just trigger a real matching event (e.g. cross a
linked geofence) and watch for the notification.
