## **Description**

Fixes an issue where the price and percentage display would remain stuck
at crosshair hover values after changing timeframes in the advanced
chart.

**Issue**
When a user:

Hovers over the chart (which sets crosshair data)
Changes to a different timeframe (or clicks the same timeframe again)
The price and percentage display would incorrectly show the old
crosshair values instead of resetting to show the current values for the
new timeframe.

The crosshairData state was not being cleared when changing timeframes.

**Solution**
Added setCrosshairData(null) in the handleTimeRangeSelect callback to
clear crosshair data whenever the timeframe changes.

> [!NOTE]
> **Low Risk**
> Low risk UI-state fix that only clears `crosshairData` when switching
chart time ranges, affecting display state but not data fetching or
persistence.
> 
> **Overview**
> Fixes the advanced token chart header getting stuck showing crosshair
hover price/percentage after changing timeframes by clearing
`crosshairData` in `handleTimeRangeSelect` before updating the selected
range and tracking the event.
