Add locale-aware date ordering support #58

Description:

Currently, the date picker uses a hardcoded day/month/year order which doesn't respect user locale preferences.

Key Changes:

• Added useLocaleOrdering flag to respect system locale date format
• Defaults to false to maintain current behavior
• Supports MDY, DMY, and YMD formats based on user locale
• Includes sample implementation and tests

Motivation:

Different cultures have different conventions for displaying dates
Some locales use day-month-year (DMY) order (e.g., UK, Europe)
Others use month-day-year (MDY) order (e.g., US)
Some use year-month-day (YMD) order (e.g., East Asia)

I can do a PR that adds support for automatic locale-based date ordering while maintaining backward compatibility. What do you think about this?
