fix dark mode btn rotation angle on toggling

[mesumittiwari]

Which issue does this PR close?

• Closes [BUG] Inverted Dark Mode Icon #425

Rationale for this change

The theme toggle button in both desktop and mobile navigation was displaying an inverted/upside-down moon icon in light mode due to a 180-degree rotation being applied. This created a poor visual experience and made the icon appear broken or incorrectly oriented. The fix maintains the smooth rotation animation while ensuring the moon icon displays correctly in its upright position.

What changes are included in this PR?

• Fixed desktop theme toggle: Changed moon icon rotation from rotate-180 to rotate-[360deg] in ModernNavbar component
• Fixed mobile theme toggle: Applied the same rotation fix to the mobile menu theme toggle
• Preserved animation: Maintained the smooth 500ms transition duration for the rotation effect
• Maintained functionality: No changes to theme switching logic or state management

Are these changes tested?

Screenshot:

Manual testing performed:

• Verified moon icon displays upright in light mode (both desktop & mobile)
• Verified sun icon displays correctly in dark mode (both desktop & mobile)
• Confirmed smooth rotation animation still works when switching themes
• Tested theme persistence across page refreshes
• Verified no console errors or warnings

Browser compatibility tested:

• Chrome (desktop & mobile emulator)
• Firefox

Are there any user-facing changes?

Yes - Visual improvement only:

• Moon icon now displays correctly (upright) in light mode instead of appearing inverted
• Maintains the smooth rotation animation users expect when switching themes
• No functional changes to theme switching behavior
• No API changes or breaking changes to any components
