feat(ui/battleship): integrate BattleshipBoard and metadata-driven placement/battle flow

- Added metadata state to App and wired incoming match metadata.
- Added Fleet + FLEET_ORDER in BattleShipBoard to drive ship placement order.
- Added nextShip + nextShipSize calculation for guided placement.
- Updated handlePlace and handleShoot to send structured payloads (action + data).
- Added lobby/placement/battle status messages.
- Updated grids to use shipBoard + shipName/shipSize props instead of generic grid.
- Fixed metadata access (state.Metadata vs state.metadata).
- Consolidated PlacementGrid usage and disabled it during battle phase.
- Added logging for debugging incoming battleship boards.
