AI Summary: Implement a Godot (GDScript) function `login(uid)` that calls a Django REST API's `/login` endpoint with a given UID, handles authentication, and returns a JWT token upon successful login. The function should also emit a `login_failed` signal with an error message if the login fails. The API response is expected to be a JSON object with a "token" field.

AI Summary: Add placeholder AudioStreamPlayer3D objects at key landmarks within the existing Three.js 3D campus map of the Unimate wayfinding app. These placeholders should include stub `play()` functions to be implemented later, enabling future integration of voice guidance features. The implementation should ensure that calling `play_start_navigation()` triggers the `play()` signal from the assigned AudioStreamPlayer3D.

AI Summary: Implement a Godot GDScript (UserSession.gd) that fetches timetable data from a `/timetable` API endpoint using a stored JWT. The script should then store the timetable data as a dictionary and emit a `timetable_ready` signal to notify the UI.
