fix: normalize opponent ID case and update battleship drag behavior

- Change Maurice's opponent ID from "Maurice" to "maurice" for consistency
- Replace Phaser disableInteractive/setDraggable with removeInteractive for fleet locking
- Update development server port from 8000 to 3000 in start_web.sh
