refactor(game): unify move handling using typed payloads and remove UI-driven handlers

- Removed onCellClick from TicTacToeGameProps and migrated move sending inside TicTacToeGame
- Updated TicTacToeGame to:
  - import TicTacToePayload
  - use movePayload() builder
  - send moves using handleMove() with matchId + sendMatchData
  - remove old matchId destructuring duplication

- Updated BattleshipGame to:
  - import BattleshipPayload
  - use placePayload() and shootPayload() helpers
  - collapse place and shoot handlers into a single handleMove()
  - send typed payloads instead of raw objects

- Updated App.tsx:
  - Removed handleCellClick and no longer pass onCellClick down
  - Created typed ticTacToeProps and battleshipProps without UI callbacks
  - Cleaned unused state and simplified board rendering
  - Use {...commonProps} to propagate shared game state

- Updated props:
  - Removed TicTacToeGameProps.onCellClick
  - BattleshipGameProps continues to extend GameProps

- Removed duplicate MatchDataModel definition from interfaces/models
- Fixed imports to use revised models and payload types

This refactor completes the transition from UI-triggered handlers to
typed action payloads per game, significantly improving type safety,
consistency, and separation of concerns.
