fix: 移除logo白色背景 + 优化登录页面UI和中文化 

Logo修复:
  - 移除 logo.svg 中的白色背景矩形 (fill="#ffffff")
  - Logo 现在为透明背景，在深色主题上正确显示

登录页面优化:
  - 添加 "iAgent" 品牌标题 (28px, bold, 带字间距)
  - 副标题改为中文 "服务器集群运维智能体"
  - 表单中文化: 邮箱/密码/登录
  - 错误提示改为带背景色的卡片样式 (红色图标+文字)
  - 添加邮箱输入框 placeholder (user@example.com)
  - 密码框支持回车提交
  - 底部提示: "账号由管理员在后台创建或通过邀请链接注册"
  - 限制表单最大宽度 360px，外层改用 SingleChildScrollView 防溢出

用户账号说明:
  App 端不提供自助注册功能，用户账号通过以下方式创建:
  1. 管理员在 Web 后台 (用户管理页) 直接创建
  2. 管理员发送邀请链接，用户通过链接注册
  3. 通过 Web 端自助注册 (可选填公司名创建新租户)
