fix(branding): 重新生成全平台图标 — 基于更新后的Logo SVG v2

## 变更
- genex-icon.svg: viewBox 72→100, 去除圆角路径, 调整notch半径和形状尺寸
- genex-04.svg → genex-lockup.svg: 重命名, 缩放0.7x, viewBox 380→200

## 重新生成的资源 (80+ 文件)
- 3 Flutter apps × (5 Android mipmap + 15 iOS AppIcon + 3 LaunchImage + 2 assets)
- admin-web: favicon.ico/png, logo.png, logo_icon.png, icon-512.png, SVG源文件
