nice theme for codemirror

[siIverfish]

I'm changing app.html to be mostly dark, so we need a dark-mode theme for codemirror. i decided so solve this problem by delegating it to you bc you javascripted the codemirror editor.

So I'm thinking we can have dark/light mode be decided using user OS settings. We can then add a colorscheme selector, my ideas for colorschemes are: GitHub (Dark & Light), catppuccin (late & mocha), and no vscode cuz no one wants to port the light theme for it.
