- Created new Player.tsx component to handle username input, auto-connect, matchmaking, and logout.

- Moved all login, session UI, mode selection, and matchmaking logic from TicTacToe.tsx into Player.tsx.
- Added onMatchDataCallback prop support for Player component.
- Cleaned up TicTacToe.tsx by removing duplicated login/matchmaking UI and connect logic.
- Improved auto-connect on mount via Player.tsx.
