界面优化

[skelfu]

1. 修改界面的字体尺寸。
2. 图例字体族类型改为等宽字体，优化饼图图例的格式化，数据能更好的对齐.
3. 调整饼图边界，默认情况下图例不会遮挡饼图。取消了光标在图表中时不必要显示的x=*** y=***。
4. 取消Steamer Mode的默认开启。
5. Overlay菜单中添加文本框展示本地网页服务的地址。
6. 配置文件中Cargo.toml的edtion从2021修改为2024，使用2021在我的设备上编译报错。
7. 没学过rust，纯问ai现学现改，有bug别找我，我也不会 (T_T)。

1. Modify the font size of the interface.
2. The font family type of the legend has been changed to a monospaced font to optimize the formatting of the pie chart legend, ensuring better alignment of the data.
3. Adjust the boundaries of the pie chart. By default, the legend will not cover the pie chart. The unnecessary display of x=*** y=*** when the cursor is on the chart has been removed.
4. Disable the default on of Steamer Mode.
5. Add a text box to the Overlay menu to display the address of the local web service.
6. In the configuration file, the edtion of Cargo.toml was changed from 2021 to 2024. When compiling with 2021 on my device, some errors occurred.
