feat: integrate PWA support with vite-plugin-pwa and remove legacy service worker files

- Added vite-plugin-pwa for enhanced PWA capabilities, including automatic service worker registration and caching strategies.
- Updated manifest configuration directly in vite.config.ts, removing the need for a separate manifest.json file.
- Removed legacy service worker and associated versioning plugin, streamlining the PWA setup.
- Adjusted UI components to reflect the new update handling mechanism for service workers.
