Minimum viable prototype of "daily challenge" feature

[bdach]

• Depends on osu-resources package with Add "daily challenge" icon osu-resources#324 for icon
• Depends on Add client/server models & operations for "daily challenge" feature #28194 for shared code / diff size reduction
• Depends on Announce currently active "daily challenge" playlist to clients osu-server-spectator#234 to actually work

This would conclude what I would consider to be the first minimal releasable increment of this feature.

The daily challenge room is not filtered out of playlists yet despite prior discussion because things are set up such that exiting out of the playlist puts you into the lobby, so it kinda makes sense to me to keep it there for now (and hiding it is a bit annoying given current setup, so if we end up redoing the screen to be a completely separate thing then it'd be wasted effort).

The diffsize is pushing it, but most of the diff is visuals and tests, so I'm hoping it won't be an issue. Am willing to split stuff out if required, just don't wanna do it without causing more ceremony than necessary (see: dependency list).

@bdach I'm not sure which change specifically caused this (likely the state handling of ButtonSystemState or changes to initial button width) but the animation no longer plays the first time each level of menu is shown:

master:

2024-05-23.17.22.03.mp4

this pr:

2024-05-23.17.21.06.mp4

I think it might be faster if you check on this since you're more familiar with your changes.

bfa23ec should do it I reckon. Code quality is... dubious in those parts 😅
