Esc key still hides chat when hide hotkey is set to "Not set"

[Lukeoutt]

When the hide chat hotkey in the plugin's configuration settings is set to Not set, pressing Esc still hides the chat. Setting the hotkey to Not set should fully disable the keyboard hide functionality, but the Esc fallback appears to remain active regardless.

Steps to reproduce:

1. Open the Fixed Mode Hide Chat plugin settings
2. Set the hide chat hotkey to Not set
3. Press Esc in-game

Expected behavior:
With the hotkey set to Not set, no key (including Esc) should trigger the hide chat action.

Actual behavior:
Esc still hides the chat even though no hotkey is configured.

To add to this, having the key bind not set is currently making every key hide the chat box.
