[Architecture]: Add offline support via next pwa and Firestore offline persistence

[Aditya948351]

DevPath should be fully usable on mobile devices even with spotty internet. Configure next pwa to generate service workers for caching static assets, and enable Firestore offline persistence layer so users can continue viewing their roadmaps and checking off skills without an active internet connection.

Hi @Aditya948351,

I'd like to work on this issue under GSSoC'26.

Proposed Implementation

• Review the current Next.js and Firebase configuration to identify where PWA support and Firestore initialization are handled.
• Integrate next-pwa into the application and configure service worker generation for caching essential static assets and application resources.
• Add and configure a web app manifest to improve installability and mobile PWA support.
• Enable Firestore offline persistence so previously fetched roadmap and skill data remains available when users lose internet connectivity.
• Ensure the application gracefully falls back to cached data during offline usage and seamlessly synchronizes updates once connectivity is restored.
• Verify that roadmap progress and skill completion states remain accessible and functional across online/offline transitions.
• Test the implementation under offline and unstable network conditions using browser developer tools to validate caching behavior, persistence, and overall user experience.
• Document any required configuration changes and ensure the solution remains scalable for future data growth.

This enhancement will improve mobile usability, reliability, and overall user experience for users with intermittent or limited internet connectivity.

Could you please assign this issue to me? Thank you!
