Add icon to "See payees" in Payments tab

tl;dr: Add an icon to the “See payees” button in the Payments tab.

A minor thing, but I find it very strange (and a little annoying) that “See payees” doesn’t have an icon like all the other options in its section;

Also, anecdotally, I’ve seen a few people find it difficult to spot the “See payees” option due to the lack of an icon.
