Pull Request Overview

This pull request integrates login functionality directly into the lobby screen and introduces new configuration options to control authentication UI elements. The main goal is to provide a more streamlined authentication experience by allowing users to log in from the lobby screen rather than through separate dialogs.

Key changes include:

• Replaced the separate "Wait for Owner" dialog with integrated login buttons in lobby screens
• Added new lobby configuration options (showLogIn, showHangUp) to control authentication UI visibility
• Refactored authentication state management to use flags instead of dialog-based approach
