Crepe appends the slash menu to .milkdown and (in this version) doesn't expose
a way to portal it to <body>, so it's clipped by the editor's scroll box. That
box sat inside the card's p-5 padding, so the menu cut off at the padding edge.
Move the padding onto the ProseMirror content instead and drop the redundant
inner scroll container, so the menu's clipping bounds become the full card.
