* Add basic PWA support
See: https://github.com/gpxstudio/gpx.studio/issues/38
This will add a basic manifest.json file to the response that creates an
installable PWA.
It still needs to be internationalized.
* Refactor PWA integration and update dependencies
- Removed @vite-pwa/sveltekit dependency and related configurations from package.json and vite.config.ts.
- Added prebuild script to generate PWA manifest before build.
- Moved the manifest link to hooks.server.js and included Apple touch icon.
-Added images for various platforms. Images were generated with https://www.pwabuilder.com/imageGenerator
* use svg icon, fix urls, and remove generated manifest files
