Pull Request Overview

This PR adds support for a multi-scale 24-hour tick formatter to improve timeline visualization. The change introduces an adaptive tick formatting function that automatically selects appropriate time formats based on the granularity of the data (milliseconds → seconds → minutes → hours → days → months → years), and enables its use in the WUTimeline component.

Key changes:

• Created a new multiScale24Hours() formatter with adaptive time formatting logic
• Added tickFormatFunc() method to allow custom tick formatting functions in Axis and ReactTimelineSeries
• Updated WUTimeline to use the new multi-scale formatter instead of a fixed "%H:%M" format
