* Use local copy of workbox service worker scripts
* Refactor workbox integration:
- Only add prod js, without maps. Reduces the size from 170k to 24k
- Removed it from build. As it is small now, we can add it to source, and have a script to just update it whenever it is required
- Fixed relative paths in navidrome-service-worker.js, should now work with BaseUrl != ''
