feat(battleship): add complete Battleship game UI with placement & battle phases

- Implement BattleshipBoard with phase-based rendering (placement/battle) - Add PlacementGrid for ship placement interaction - Add ShotGrid for firing UI with turn validation - Integrate match metadata (pX_placed, pX_ready, phase) - Connect UI to Nakama sendMatchData (place + shoot actions) - Add real-time board rendering for ships and shots - Add status line, turn handling, and winner display - Ensure compatibility with new backend ApplyMove/ApplyPlacement logic
