feat(address): 支持最大地址数量设置为 0 表示无限制 (#968)

* feat(address): 支持最大地址数量设置为 0 表示无限制

- 移除角色配置中 =0 时回退到全局设置的逻辑
- 添加负数校验防止无效输入
- 更新前端文案说明 0 表示无限制

* fix(admin): 修复 maxAddressCount 验证逻辑，禁止负数和非对象输入

在 saveRoleAddressConfig 接口增加 configs 参数类型校验，
确保其为有效对象而非数组或 null。同时在 UserSettings 模型中
验证 maxAddressCount 必须大于等于 0，防止无效数据进入系统。

* style: 修正错误的缩进
