Better handling for append-only services

[ZacSweers]

Some services, like Refind's API, only give you the current three, and then update sometime in the future. These today would basically be limited to only showing three items at a given point. It would be nice to show these in a way that we keep a growing cached list of items prior.

This could be a good use case for the paging arch component library since the items wouldn't be grouped by session ID or ever invalidate.

Could also let us be more efficient in items with non-changing viewmodel data like dribbble (they have likes and whatnot, but we don't show it in the display).
