feat: CLI 改密、自定义 TLS、移动端适配与扩展校验

- 新增 one-kvm user set-password（交互式），改密后吊销该用户全部会话
- /api/config/web 支持 PEM 证书/密钥上传与清除，响应含 has_custom_cert
- 移动端：ActionBar 溢出菜单、ATX/粘贴底部 Sheet、BrandMark 与控制台等响应式优化
- GOSTC：校验服务器地址非空，管理器启动条件与 HTTP 热更新一致
- RustDesk：中继密钥 relay_key 校验为标准 Base64 且解码后恰好 32 字节
- StatusCard、InfoBar：合并精简冗余状态信息
