Add Dark Mode Toggle for Improved User Comfort in Low-Light Environments

[Aman-G-upta]

The current interface of OpenSMP is only available in light mode, which may lead to eye strain for users, especially during prolonged use in low-light environments. Dark mode is a popular feature that allows users to switch to a darker color scheme, making it easier on the eyes and enhancing the user experience.

Proposed Solution:

Add a Dark Mode toggle button to the top right of the navbar, near the "Sign In" button, so users can easily switch between light and dark themes.
Implement the dark theme with a color palette that maintains readability and visual consistency with the current branding.
Save the user’s theme preference (light or dark) in local storage to ensure that their choice persists across sessions.

Expected Outcome: This feature will provide a more comfortable viewing experience for users in various lighting conditions, reduce eye strain, and modernize the site interface by offering theme customization. A toggle for dark mode would make OpenSMP more accessible and user-friendly.
