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.
