Add a way to see who reacted to a post

Pitch

From https://urusai.social/@rosey/109776331068351248

This proposes 2 things:

1. A "reactions list page", similar to {statuslink}/favorites or {statuslink}/reblogs which shows who reacted with what
2. Adding the information about who reacted to the post to the tooltip of the reaction

I think we can just add this information to the title attribute of the reaction, no need to go all-out like discord does with a whole overlay+tooltip system (for now).

Motivation

It's great to know who reacted to things!
