feat: 增强代理和玩家管理功能

- 在 SyncAdminAuthorizationCommand 中新增对代理线路和结算菜单操作的同步功能，确保缺失的菜单操作行能够被创建。
- 更新多个控制器中的权限检查逻辑，使用 hasPermissionCode 替代原有的权限验证方式，提升权限管理的灵活性。
- 在 AdminPlayerStoreController 中引入对玩家创建能力的验证，确保只有具备相应权限的管理员能够创建玩家。
- 更新请求验证逻辑，新增 credit_limit、rebate_rate 和 extra_rebate_rate 字段，以支持更细粒度的玩家管理。
- 在 AdminUser 和 AgentNode 模型中增强角色与用户的权限管理功能，支持更细粒度的权限控制。
