📅 Feature Request: Add Date Picker for Date Input

Description:
Currently, users are required to manually enter the date in a specific format (DD.MM.YY) when generating a transport challan. This manual input process is prone to formatting errors, invalid dates, and unnecessary confusion, especially for users who are not familiar with the required format.

To enhance usability and improve data accuracy, it is recommended to integrate a date picker widget. This feature would allow users to select a date from a visual calendar, eliminating errors and making the app more intuitive and user-friendly.

Benefits:

• ✅ Reduces formatting and typing errors
• ✅ Ensures only valid dates are selected
• ✅ Enhances user experience with a clean and interactive interface
• ✅ Saves time during data entry
• ✅ Makes the application accessible to a wider audience, including those less tech-savvy

Suggested Implementation:

• Use the widely adopted tkcalendar Python library for adding a DateEntry widget.
• Ensure the selected date is formatted as DD.MM.YY to maintain consistency with existing data handling.
• Integrate the widget seamlessly with the current application structure.

Expected Outcome:

• The date input field will transform into an interactive calendar widget.
• Users will be able to click and pick a date easily without worrying about format or typing errors.
• The application will offer a more professional and polished interface.
