feat: optimize PWA service worker update strategy for better caching

Improve service worker update handling to fix caching issues during development:
- Add skipWaiting and clientsClaim in Workbox config for immediate SW activation
- Remove user confirmation prompt and switch to silent automatic updates
- Replace hourly polling with visibility-based update checks via visibilitychange event

This resolves the issue where web updates would not take effect without manual cache clearing.
