Who would have guessed that `Schedule` calls were there for a reason!
I've tidied things up. Most of the changes I've made here are not
required – the schedule is the main thing here. The reason the sound was
playing is because one-too-many schedules was removed causing beatmap
updates to update carousel specifics while still at the player loader
screen.
Note that the selection sound still plays on returning to song select,
but this is not a regression. I'm looking at fixing this in a separate
PR because I'm in a good place as far as understanding the logic right
now and it would be a waste to leave it broken.
Closes https://github.com/ppy/osu/issues/25875.
Following discussions on discord, this seems like the most agreed upon
value. Increasing this is important so that imported legacy scores don't
lose too much value.
