Backend Update

Hello,

I updated backend code for the app, which will allow me to add some new features I have lined up (more info in PS). The plan is to add a category lock, so you can "lock in" any of the cards so it doesn't change when you generate new idea. Also wanted to add a dropdown menu to select from all available cards in any category.

PS: For Godot devs: I basically rebuild the whole scene, using only nodes that inherit from Control. All UI nodes interface scales pretty good with resolution, turns out.
