refactor(coverage): 资产覆盖图改用 G6 真力导向布局

- 渲染引擎 xyflow+d3-force(静态坐标) → @antv/g6 d3-force 布局
  + drag-element-force/drag-canvas/zoom-canvas：拖拽实时重排、缩放平移
- 动态 import @antv/g6(避开 SSR/静态导出)，顶层仅 import type
- 折叠/分页、点击抽屉、展示更多逻辑与配色语义原样保留
- 轮询改为按需刷新(避免力导布局被反复打断)
- 依赖：声明 @antv/g6，移除不再用的 d3-force/@types/d3-force
