[style]: Responsive Header and Toggle Button Adjustment for Tablet View

[shivhere007]

What's the style idea?

This update aims to enhance the user interface of the "DevDisplay" platform on tablet devices. Adjustments focus on aligning the header elements and optimizing the light/dark mode toggle button for screens with a max-width of 768px. These changes ensure that the header is clean, centered, and free of overflow issues while the toggle button remains accessible without crowding, providing a seamless experience for tablet users.
