Add View/Edit Moderators button to create listing screen

This came in as a suggestion and would be nice to do.

Are we talking a button that would just open the Moderation tab in Settings? That's easy-peasy.

Or, are we talking actually viewing and modifying the mods within the already ridiculously complex listing modal? That would be ambitious.

Just a button, I think. Maybe with text saying how many moderators are currently on the listing.

While it might be nice to show details about the current moderators on a listing, then we get into all kinds of async issues along with stuffing a lot of extra visual complexity into an already very full screen.
