Implement pagination for scopes index

Is your feature request related to a problem?

When an organization has a lot of scopes (let's say more than 200), the scopes index page in BE takes time to load. In general, the scopes are not scalable (i.e. in my interests in user account).

As Decidim is being used by more and more institutions (cities, counties, etc.), the scope will need to adapt to new areas, with more and more scopes needed. For exemple, a county might want to have all of its cities displayed as scopes, but with more than 1000 scopes, the scope index page is crashing.

Describe the solution you'd like

To solve this scope scalability problem, it would be useful to add pagination to the /admin/scopes page, so that in case of a lot of scopes, the loading of the page is not impacted.

Additional infos

In our use case, this feature would be used to display an interactive map with geocoding available with this module : https://github.com/OpenSourcePolitics/decidim-module-homepage_interactive_map

Describe alternatives you've considered

Add this feature to the module.
