[Request] Check if dmnt:cht service exists before calling dmntchtInitialize()

[masagrator]

This is for people that use GDB. Accidentally opening it when GDB is turned on in Atmosphere settings results in overlay stuck in infinite loop and only what we can do is to restart Switch.

When dmnt:cht is not detected, just point to empty GUI with simple "dmnt:cht is not running".

Here is another beta build (v1.0.6-beta3) with pink highlight color. This doesn't call dmntinitialize() if dmnt:cht is not running and will display 'Cheat Service Unavailable!' EdiZon-Overlay.zip

It works correctly. Thanks.
