Pagination components refactoring

[jahow]

Description

This PR is a refactoring aimed at simplifying and homogenizing pagination across the project:

• a Paginable interface is introduced; any component that can handle pagination, be it async or sync, should implement this API
• all pagination widgets were brought back into the ui/layout module, there's 4 of them (prev/next buttons, pagination dots, page numbers from the Editor and page selector from the organizations page in the Datahub)
• all paginations widgets now use the Paginable API directly; this avoid redundant code in every component like it was before
• all pagination widgets are grouped together in Storybook and use a mock paginable component
• improved styling of the pagination buttons component to match the mockup:
  

Architectural changes

Moved several components from ui/elements to ui/layout
