only fetch claimants for set requests on set requests page

eliminates a ~40ms query from my profile page

Verified locally.

Tangentially related: it seems kinda weird that on every page that doesn't have a set, we're making a client-side call to set-requests.php. We should probably consider refactoring this to live entirely on the server - the content being rendered from the response is causing a tiny layout shift because it isn't initially painted to the screen.

That logic has been there since it was introduced in #378. I assume it's a result of mimicking the set rating logic that's present when the game does have a set. That was eliminated in #960.

Yep, not suggesting at all it was introduced by this PR or should even change in this PR. Just more of a note we should probably consider refactoring sometime soon-ish.
