Add Windows app download button to quickstart page

[t0mdavid-m]

Summary

Added functionality to the quickstart page to allow users to download a Windows version of the OpenMS application directly from the Streamlit interface.

Key Changes

• Imported Path from pathlib for file system operations
• Created a cached resource function load_windows_app_bytes() that reads the Windows app binary from /app/OpenMS-App.zip if it exists
• Added a Streamlit download button on the main quickstart page that displays when the Windows app file is available
• The download button is styled with a material download icon and serves the file with the correct MIME type

Implementation Details

• Used @st.cache_resource decorator to cache the app bytes in memory, avoiding repeated file reads
• The function gracefully returns None if the app file doesn't exist, preventing errors in environments where the Windows app isn't available
• The download button only renders when the app file is present, ensuring a clean UI in all deployment scenarios

Summary by CodeRabbit

• New Features
  • Quickstart page now features conditional download functionality for the OpenMS-App ZIP artifact. When the artifact is available on the system, users can directly download the ZIP file from the quickstart interface. If unavailable, the download option is hidden, maintaining a clean user experience without unnecessary UI elements.

📝 Walkthrough

Walkthrough

The quickstart page now includes conditional rendering of a download button for OpenMS-App.zip. A cached loader attempts to read a Windows ZIP artifact from a fixed filesystem path, and the download UI is displayed only if the artifact is successfully loaded.

Changes

Cohort / File(s)	Summary
Quickstart Download Feature content/quickstart.py	Added Path import and implemented a cached loader that reads a Windows ZIP artifact from the filesystem. Conditionally renders a download button for OpenMS-App.zip when the artifact is available.

Poem

🐰 A button hops onto the page so bright,
When ZIP files hide on the filesystem's sight,
With caching and checks, the artifact's found—
Download awaits, no error's around! 📦
