UNO-style UX rollout: Lobby, Matchmaking, Profile

- Lobby: the two hero actions (random / create room) are now tactile press-3d
  rounded-3xl with tinted icon chips.
- Matchmaking: seat slots use the Avatar frame with a gold border when filled
  (dashed placeholder when empty + spring pop-in); cancel/start/upgrade buttons
  are tactile.
- Profile: added a level badge on the avatar (casual-game style).

Verified: tsc + next build clean; web rebuilt :1500.
