This aims to bring some conformity to naming to make it easier to
understand component structure for new components.
Renames are pulled out of the song select v2 changes and are more
relevant there due to many new classes being added.
- `V2` suffix is dropped, with v2 components being moved to a relevant V2 namespace.
- Related classes have a prefix of the area they are used.
- Experimenting with using partial/nested classes in the song select v2 implementation.
Not committing to this yet but want to see how it plays out.
- Moved base carousel components to a generic namespace to avoid confusion with actual beatmap carousel implementation.
Saves having this defined in 20+ places. If we ever make any changes to
shear, it's 100% going to need to be applied to every usage (there will
never be a case of multiple different shears in the game).
Also fixes a mismatching definition in `ShearedNub`.
`CommentReportButton` is pretty cursed but I guess I can see why it is
like it is. Short of inlining it into `DrawableComment` this is probably
the best escape hatch (which I wouldn't be against doing, by the way,
just not sure it's the most productive use of time unless review
feedback comes in saying that would be a better path forward).
The previous logic was very wrong, as the check would only occur on each
beat. But that's not how kiai sections work – they can be placed at any
timestamp, even if that doesn't align with a beat.
In addition, the rate limiting has been removed because it didn't exist
on stable and causes some fountains to be missed. Overlap scenarios are
already handled internally by the `StarFountain` class.
