Service Worker Improvements and Chunk Load Error Handling

[seer-by-sentry]

Fixes ECENCY-NEXT-WKD. The issue was that: Service worker cache invalidation failure due to dynamic build IDs and aggressive precaching of non-existent chunks.

• Implements a ServiceWorkerManager component to handle service worker lifecycle and updates, ensuring new deployments are reflected by reloading the page.
• Adds a custom service worker (custom-sw.js) to skip waiting and claim clients immediately upon activation, and to clean up old caches.
• Sets up a global error handler to catch ChunkLoadError exceptions, which occur when the user has a stale service worker or cached HTML, and reloads the page to fetch the new version.
• Configures next-pwa to use the custom service worker and customize runtime caching strategies, including network-first for JavaScript chunks to prevent stale chunk errors.
