NeoUI scoreboard

[nullsystem]

Replace the current SDK-ish scoreboard with a NeoUI scoreboard.

Parity features with the current scoreboard:

• Left-right panels for in-game teams, bottom panels for unassigned/spectators
• Color styling follows green for Jinrai, blue for NSF, gray for unassigned, and orange for spectators. Except if it's DM it's a non-team aligned color for in-game players
• cl_neo_hud_team_swap_sides 1 - if playing and NSF, NSF on left, Jinrai on right. Otherwise for others Jinrai on left, NSF on right.
• Show avatar and dead icons, don't show avatar if local player wanted to hide it (neo_show_scoreboard_avatars and cl_neo_streamermode)
• Players information given equal to old scoreboard

Additional features that's not present in the current scoreboard:

• Right-click for a mouse interactable scoreboard
• Replace in-game main menu's "players list" which just deals with mute/unmute and instead deal with it within the scoreboard
• Lobby ready-up status and action in scoreboard
• Player card for bigger avatar + name and set of actions
• Copy other player's crosshair
• Player profile button
• Player friend management button
