Improve information displayed in a network's sites list table

* Better support for arbitrary domain/path combinations by displaying the URL in the primary column rather than Path or Domain.
* Show a cached count of total users per site as a more useful data point rather than the first 5 users.
* Clear that cached count of users for a site when a user is added to the site via `add_user_to_blog()`.

Props @ocean90.
Fixes #32434.
