refactor: extract common code in mod pages and model

This creates a hierarchy in which ModPage and ModModel are the parents
of every mod provider, providing the basic functionality common to all
of them.

It also imposes a unique .ui file (they were already equal before, just
duplicated basically) on all mod providers.
