[Bug]: V5版本设置rotation后 缩放中心定位不正常

### Describe the bug / 问题描述

new Graph({
// renderer: () => new SVGRenderer(),
container: context.container,
animation: true,
background: "transparent",
padding: 20,
rotation: isLandscape ? 90 : 0,
autoFit: {
type: 'view',
options: {
// 仅适用于 'view' 类型
when: 'always', // 何时适配：'overflow'(仅当内容溢出时) 或 'always'(总是适配)
direction: 'both', // 适配方向：'x'、'y' 或 'both'
},
},
zoomRange: [0.2, 1],
behaviors: [
{
type: 'drag-canvas',
enable: true,
key: 'drag-behavior',
},
...context.getZoomBehaviors(),
],
});
设置rotation后 ，图形进行了旋转但是 autoFit失效，显示靠边。且缩放时，缩放中心定位不正确，导致显示不对。

Start by reproducing the Graph configuration shown with rotation set to 90, autoFit enabled, and zoom behaviors active. Trace the rotation, autoFit, and zoom-center handling from the Graph entry point; done means the rotated graph fits correctly and zooming remains centered on the intended location.
