Fixed Radial Menu Crash (#795)

Updated `InputSettings.RadialMenuSettings` to properly initialize `radialActions` as a mutable ArrayList to prevent compilation errors and added missing import for `java.util.ArrayList` in InputSettings.java.

Tested on Steam Deck only and verified it works, unsure about other input methods. While this patch doesn't change device-specific functionality, I would still suggest testing it on other controllers.
