Display a modal of mutual subscribers to be displayed when clicking 'other' on `m-channel__mutualSubscriptions`

Goal

Now we have 'also subscribed to' blocks on channels, we want to expand to be able to see more than 2 results.

What needs to be done

We already have a modal that displays for subscribes on notifications, this is just a time ordered list. Modify this modal to support mutual 'also subscribed to'. The backend needs a slight tweak to support pagination.

QA

The modal display when relevant.
