labelalias should have the option to not affect hover labels or unified hover title

Currently, xaxis.labelalias/yaxis.labelalias changes both the axis tick labels and the hover labels / unified hover title. In some use cases, users want to display friendly axis labels but keep the hover title showing the raw data value.

Using tickvals/ticktext is a workaround but requires manually updating tick mappings if the axis data changes dynamically.

The new unifiedhovertitle.text allows formatting of the hover title, but it does not support mapping from x/y values to aliases.

Proposed solution:
Add an option for labelalias to only affect axis ticks. Hover labels and unified hover title should still display the underlying raw value unless explicitly overridden.

首先在仓库中定位对 xaxis.labelalias、yaxis.labelalias、悬停标签和 unifiedhovertitle 的处理。确定该选项如何将别名限制为坐标轴刻度标签，然后验证除非被显式覆盖，否则悬停标签和统一悬停标题会保留原始值；为两种轴类型和动态数据映射添加或更新测试。
