feat: implement comprehensive PWA force update system

- Add UpdateManager and UpdateChecker for automatic version detection
- Add post-build script for meta.json generation and version injection
- Enhance Service Worker with version-aware caching
- Add .htaccess configuration for proper cache control

This ensures all users receive the latest version after deployment
without manual cache clearing.
