fix: clic app icon is not showing

[anikdhabal]

What does this PR do?

Fixes the Clic app icon not showing in the app store by adding the missing icon.svg and reorganizing screenshot files to follow the expected static folder structure.

• Fixes Clic images is not in production app store #27009

Summary of Changes

• Bug Fix: Added packages/app-store/clic/static/icon.svg - the icon was missing, causing it not to display in the store
• File Reorganization: Moved and renamed screenshot files from root (preview*.png) to static/ folder (1.jpg-4.jpg) to match the expected app store structure
• Config Update: Updated DESCRIPTION.md to reference the new file names

Mandatory Tasks (DO NOT REMOVE)

• I have self-reviewed the code (A decent size PR without self-review might be rejected).
• I have updated the developer docs in /docs if this PR makes changes that would require a documentation change. N/A - no docs changes needed.
• I confirm automated tests are in place that prove my fix is effective or that my feature works. N/A - visual/asset change, CI passes.

How should this be tested?

1. Navigate to the Cal.com app store
2. Find the Clic app integration
3. Verify the app icon is now visible on the card
4. Click into the app details and verify the 4 preview screenshots display correctly

Human Review Checklist

• Verify the Clic app icon displays correctly in the app store listing
• Verify all 4 preview screenshots load correctly on the app detail page (files were renamed and moved to static/ folder)
• Confirm the SVG icon renders properly at different sizes
