fix(objects): replace Area2D.input_event with _input() for reliable Android touch

Browse Source 
Area2D.input_event is unreliable on Android with gl_compatibility renderer.
Switched to manual _input() hit detection using canvas_transform coordinate
conversion, consistent with the DragDropComponent approach already used in
this project.
