[FEATURE] - Add persistent light/dark theme toggle

[ash1shkumar]

Is your feature request related to a problem?

Currently, the application does not provide users with a light/dark theme toggle option after authentication or while using the dashboard.

The landing page and dashboard use fixed themes, which limits personalization, accessibility, and overall user experience for users who prefer different viewing modes or system-based themes.

---

Describe the Solution

Add a global light/dark theme toggle across the application, especially after clicking "Get Started" and entering the dashboard.

Suggested implementation:

• Add a theme toggle button in the navbar/dashboard header
• Persist user preference using localStorage
• Support automatic system theme detection using prefers-color-scheme
• Apply smooth theme transitions across pages

Key Design Decisions

• Read prefers-color-scheme on first load as the default theme, then persist the user’s selection in localStorage under a key like ms-theme
• Toggle a dark-mode class on .landing-root to keep styles scoped properly and avoid affecting unrelated dashboard/app layouts
• Place the toggle beside the “Get Started” button in the navbar using the same typography and minimal aesthetic already used throughout the site
