fix: LEAP-1819: Prevent drawing actions outside the stage area

[Gondragos]

Added a new inStage method to verify if events occur within the stage boundaries. Updated multiple event handlers (e.g., mousedownEv, clickEv, dblclickEv) to halt actions when the event is outside the stage dimensions, improving boundary validation.
