## panel and toggle between Login and Register modes via signal emission.
##
## Key tests:
##  - AuthPanel starts hidden.
##  - LoginButton press opens the panel in Login mode.
##  - RegisterButton press opens the panel in Register mode.
##  - Clicking Login while in Register mode switches back to Login mode.
##  - Clicking Register while in Login mode switches to Register mode.
##  - The ModeToggle CheckButton no longer exists in the scene.
