Forfeit = 2x coin loss + 0 XP (no kot); end-of-game roster + add friend

Forfeit penalty reworked (client + server gamification, in sync):
- Surrendering team loses DOUBLE the entry coins; winner takes the stake.
- Forfeiter earns NO XP. No kot is applied or mentioned anymore.
- MatchSummary/Dto carry a `forfeit` flag; GameRoom.FinalizeForfeit →
  ApplyRewardsAsync(team) with Forfeit=true (dropped the kot path).
- Forfeit confirm dialogs now alert the real penalty (double coins, no XP).

End-of-game roster: SeatPlayerDto/ServerSeatPlayer + game-store SeatPlayer gain
userId/isBot. New <MatchPlayersList> lists everyone at the table on the final
screen (PostMatchRewardsModal + AI MatchOverlay) with a tactile "Add" button to
send a friend request to real (non-bot, non-self) players ("Sent" after).

Verified: tsc + sim + dotnet + next build clean; stack rebuilt :1500/:1505.
