Major refactor: Extract Database and Automation into domain-specific trait files

### Core Architecture Refactor

- Split the `Database.php` class into domain-specific traits under `GameEngine/Database/`.
- Split the `Automation` class into domain-specific traits under `GameEngine/Automation/`.
- Grouped methods by functional domain for improved maintainability and navigation.
- Preserved 100% backward compatibility.
- No logic or behavioral changes.
- Pure structural refactor.
