Zip the assets for easy download

[StanleyMasinde]

Description:

Develop a feature to bundle all generated assets (icons, manifest files, and any additional resources) into a single ZIP file for convenient download. The system should:
1. Automatically collect all generated assets, including the PWA icons and the Web App Manifest file.
2. Create a ZIP file containing the assets, ensuring a clean and logical folder structure.
3. Provide a clear and accessible download link/button for users to retrieve the ZIP file.
4. Optimize the zipping process to handle large files efficiently.
5. Ensure proper naming for the ZIP file (e.g., pwa-assets-{timestamp}.zip) for easy identification.

Deliverables

• Functionality to generate and download the ZIP file
• A robust implementation that ensures all necessary files are included.
• User-friendly error handling for cases where assets fail to zip properly.
