fix: use setOption() method for think-orm 4.0 compatibility

- Use setOption() instead of direct property assignment
- Implement initialize() method for model configuration
- Prevent model data pollution as per think-orm 4.0 upgrade guide
- Fix table name fallback when rules_name is null

According to think-orm 4.0 official documentation:
"如果需要在模型内获取或设置模型属性的话改为使用模型的getOption或setOption方法"

This resolves:
- WeakMap initialization errors
- array_search type errors
- Table name configuration issues
