Remove deprecated streamsaver dependency

Summary of Changes

Hello @eugenioenko, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on removing the deprecated streamsaver dependency from the web-app. This involves not only deleting the dependency from configuration files but also re-architecting the file download mechanism to use standard browser APIs, ensuring the application remains functional without the removed library.

Highlights

• Dependency Removal: The streamsaver dependency and its associated TypeScript types have been completely removed from the project's package.json and package-lock.json files.
• File Download Logic Re-implementation: The toFile utility function in web-app/src/App.tsx has been re-implemented to no longer rely on streamsaver. It now uses native browser APIs (ReadableStream, Blob, URL.createObjectURL, and programmatic <a> element clicks) to handle file downloads.
• Transitive Dependency Updates: The package-lock.json file has been updated, reflecting the removal of streamsaver and including various minor version bumps for @babel and brace-expansion related packages, likely due to a npm install or yarn install run after the primary dependency removal.

Code Review

This pull request removes the deprecated streamsaver dependency. The core change involves a rewrite of the toFile function in App.tsx. While the new implementation is functional and handles abort signals, it now accumulates the entire file content in memory before initiating a download. This is a significant change from streamsaver's streaming approach and could impact performance for large files.
