PWA Offline Support with Service Worker Caching

It would be great to have the ability to enable full PWA (Progressive Web App) capabilities for Base44 apps, specifically service worker support for offline caching. This would allow apps to function (at least partially) without an internet connection — showing cached data, queuing actions for sync, and providing a seamless experience for users in low-connectivity environments. This is especially important for field-based apps where users may be in areas with poor connectivity. The manifest.json is already generated, so adding service worker support would complete the PWA experience.
