Refactor quick action button components

[bracesproul]

These components are not great from a UI perspective. They currently are just a styled div. We should refactor to ideally be a shadcn component (if nothing exists, you can make one from scratch. This is a last resort though). The goal is to have these contain smooth transitions when opening. I also like how OpenAI manages sending the actions, where clicking on an option converts it to an arrow button you need to click again to actually trigger the request. (see video)

We should also make it a shared component for code & writing quick actions, instead of two unique components.
