Icon generation

[StanleyMasinde]

Description:

Implement functionality to generate all required PWA icons from a single uploaded square image. The system should:
1. Accept a high-resolution square image upload (e.g., PNG).
2. Generate icons in all required sizes and formats, including those specified in the Web App Manifest (e.g., 48x48, 72x72, 96x96, 144x144, 192x192, 512x512).
3. Ensure proper file naming and structure to align with PWA requirements.
4. Provide feedback or error messages if the uploaded image does not meet the minimum resolution or aspect ratio requirements.
5. Compress and optimize the generated icons for performance without compromising quality.

Deliverables:
• Functionality to upload an image and generate icons.
• A folder containing the generated icons, ready for inclusion in the app.
• Automated updates to the Web App Manifest to include the generated icons.
