fix(web-app): remove unused sqlite.worker.js and wasi-dummy.js, update Config.kt and service worker logic

- Deleted `sqlite.worker.js` and `wasi-dummy.js` to clean up outdated resources.
- Updated `Config.kt` to use a shared `Json` instance for deserialization.
- Revised service worker for cache versioning and to bypass caching of `web-app.js` and `.map` files.
- Enhanced debug logging and improved handling of uncaught errors in new `sqlite.worker.js`.
