refactor: improve error handling and initialization in frontend tasks

Updated PingViewModel to reset errorMessage on each task execution and provide detailed error messages. Enhanced SQLite worker initialization with manual WASM binary loading and improved error handling. Adjusted Gradle tasks and Webpack config for SQLite assets, ensuring seamless builds. Included dummy modules to bypass Webpack resolution issues.
