"""A simple tkinter GUI to edit config.json and manage protector list.

Features:
- Edit base_url, conn_threshold, scan_interval (saved to config.json)
- Manage protector_list entries (add/edit/remove) stored in protector_list.json
- On saving base_url, attempt login via auth_session.login() and store sess_key
