chore(frontend): remove custom Webpack sqlite-wasm integration plugins and cleanup config

- Deleted `dummy.js` and its usage for sqlite-wasm integration as custom Webpack adjustments are no longer necessary.
- Removed outdated Webpack configuration files: `ignore-sqlite-wasm.js`, `ignore-sqlite-wasm-critical-dependency.js`, and `sqljs-fix.js`.
- Introduced `sqlite-config.js` for simplified and streamlined sqlite-wasm and Skiko Webpack configuration.
- Minor code formatting adjustments across frontend modules for improved consistency.
