fix(ela): 登录窗主题化 + VTK 背景稳健随主题 + 扫清所有硬编码浅色 QSS 遗漏

- 登录窗: setStyleSheet → applyThemedStyleSheet(整窗随主题, 品牌带文字用 white 关键字恒白);
  refreshBtn/errorLabel 也随主题。修暗系统下浅窗+暗 Ela 控件割裂、占位文字看不清
- VTK: 改为主题切换时重跑 rebuildCentral/rebuildDetail(走完整渲染必重绘, 兼顾 syncSystemTheme
  异步切暗时序); rebuildDetail 也按 vtkBackground 设背景
- 主动扫描修掉遗漏: dockManager 分隔条、数据集/文件列表、对象树枝/hint、空状态标题/提示 全走主题
- themed() 公共助手(给需拼接 ADS 样式的 dockManager)
