🐛 [BUG]条形图配置x轴y轴的title旋转不生效

```
import { Bar } from '@antv/g2plot';

const data = [
{ year: '1951 年', value: 38 },
{ year: '1952 年', value: 52 },
{ year: '1956 年', value: 61 },
{ year: '1957 年', value: 145 },
{ year: '1958 年', value: 48 },
];

const bar = new Bar('container', {
data,
xField: 'value',
yField: 'year',
seriesField: 'year',
yAxis: {
title: {
text: 'yAxis',
autoRotate: false,
rotation: Math.PI / 2
},
},
xAxis: {
title: {
text: 'xAxis',
autoRotate: false,
rotation: Math.PI
},
},
legend: {
position: 'top-left',
},
});

bar.render();
```
现象：方向没有变化

Start with the supplied TypeScript Bar reproduction and trace how xAxis and yAxis title options handle autoRotate and rotation. Verify the chart renders both titles at the requested angles and add or run a focused regression check for the shown configuration.
