Fixes half of https://github.com/ppy/osu/issues/24956.
The other half is high effort. The number portion is nested deeply and
with reason - depending on skin setting it changes the visual order.
I'm not sure how to fix that one, but I also think it's weird behaviour
and if people don't complain, it's probably fine to just dim the number
for consistency.
That said, the approach circle is an important one to ensure it matches
1:1, so I've fixed that here.
Stable would dim objects when they can't be hit (ie. the "miss" window
is not active yet). This was never implemented in lazer, and causes
quite large visual differences.
No one has mentioned this yet, but it will definitely be one of those
missing pieces which makes lazer feel different to stable.
