Manage a game: requests, rescheduling, cancelling

1. A request to play arrives → “Accept” or “Not now”. If you don't answer, it's accepted by itself at the time shown.
2. A player outside your level range asks to join → “Accept” or “Decline”.
3. “Reschedule” → new time. Players who signed up stay in.
4. “Cancel”: the game is cancelled and players get a notification.
5. Team complete → “Send on WhatsApp”. Friends without the app join with the match QR.

If something goes wrong

• It can't be rescheduled any more. A game can be rescheduled three times; after that it can only be cancelled.
• You no longer need the QR match. “Cancel match”: it disappears for all players.
