refactor(game): unify GameState, standardize board props, and rename game components

- Replaced multiple App-level state fields with unified GameState
- Added INITIAL_GAME_STATE and migrated App.tsx to use single game state
- Introduced GameProps as shared base props for all turn-based board games
- Created TicTacToeGameProps and BattleshipGameProps extending GameProps
- Updated TicTacToe and Battleship components to use new props
- Replaced verbose prop passing with spread {...commonProps}
- Updated renderGameBoard to use game.metadata consistently
- Renamed TicTacToeBoard -> TicTacToeGame for clarity
- Renamed BattleShipBoard -> BattleShipGame for naming consistency
- Updated all import paths to reflect new component names
- Replaced MatchDataMessage with MatchDataModel
- Moved GameState definition from models.ts to interfaces/states.ts
- Removed old board-specific prop structures and per-field state management
- Increased type safety and reduced duplication across the codebase

This commit consolidates game state flow, introduces a clean component props
architecture, and standardizes naming convention
