Dean Herbert 08c02e29b9 Fix song select scrolling performance when user has many beatmaps loaded (#37666) ...

Also fixes wrong rank showing briefly in some scenarios.

---

I'm quite confused why the overhead is in the post-async-filter
collection access, but it is. It occurs when using `MaxBy` (realm
snapshot creation), but also when calling `.Count` on the collection, or
even just accessing `sender[0]`. I tried everything, and ended up
settling on simplifying the realm part enough that we can do
post-filtering without much sweat or mess.

Tested using [this realm](https://screvillshot.s-ul.eu/YJUJ4SR1).
