Dark Mode

I would like to request the addition of Dark Mode in the myBillBook application.

Many users work long hours on billing and accounting, and a dark theme would significantly reduce eye strain, especially during nighttime use. Dark Mode also improves visual comfort and enhances the overall user experience.

Adding this feature would make the application more modern, user-friendly, and aligned with current app design standards. I strongly believe many users would appreciate this improvement.

Kindly consider introducing Dark Mode in a future update.
