feat: create shortcut component that can be used on any page

[SgtPooki]

We need to take the shortcut functionality added by #2337 and ensure it is fully encapsulated into a component/context/hook that is flexible and can be used by both files list & grid view, as well as any other components that may need it (peers page, or any future pages)

@SgtPooki should the shortcuts shown in the component be relevant shortcuts to the page its being viewed on or should it just be general shortcuts regardless of the page?

@george-hub331 I think we should probably have defaults for all pages, whatever those are, but ideally we would be able to customize them for specific actions on a page.

I imagine a react context with some hooks would be a good approach.

This is low priority though i would say.
