"""Unit tests for `ha_get_logs(source="supervisor"|"system_service")`.

Covers two REST-client paths and their tools_utility wrappers:

- `HomeAssistantClient.get_addon_logs()` — branches on `is_running_in_addon()`:
  inside the addon container hits Supervisor directly at
  `http://supervisor/addons/{slug}/logs` (the HA-Core proxy rejects the
  Supervisor token there — see #1116); otherwise falls back to
  `/api/hassio/addons/{slug}/logs` (returned as text/plain — see #950).
- `HomeAssistantClient._get_system_service_logs()` — branches on
  `is_running_in_addon()` like `get_addon_logs`: in-addon hits
  `http://supervisor/{service}/logs`; non-addon falls back to the HA Core
  proxy at `/api/hassio/{service}/logs` (#1260 fix on top of #1116 scope).
  service ∈ {supervisor, host, core, dns, audio, cli, multicast, observer}.
- The wrappers (`_get_supervisor_log`, `_get_system_service_log`) — response
  shape, tail slicing, search filter, slug-enum validation, and structured-
  error translation.
