refactor: 重组 components/ 和 pages/ 文件结构，按职责分层

components/ 拆为三层：
  - providers/   — 状态管理（App/Theme/SettingsProvider）
  - shell/       — 应用外壳（Layout/NavBar/PageDispatcher）
  - ui/          — 通用 UI 原子（FloatingPanel/LegalTextModal）

pages/ 重命名 + 重组：
  - headers/ → panels/        NavBar 触发的面板页
  - login/   → auth/          认证模块（含注册/忘记密码）
  - settings/blocks/ → sections/
  - home/components/ → panels/ features/ controls/ hooks/
    按职责分：panels(布局壳) + features(功能面板) + controls(表单控件) + hooks

其他清理：
  - 删除空占位 Test3.tsx
  - HomeContext 从 HomeContent 拆出独立文件
  - uploadValidation 内联到 ImageInput
  - 修复过时注释（useUI → controls）
