Thumbnail Generation for Webinars and Stores

This update resolves an issue where thumbnails were not being generated properly when creating new webinars or eCommerce stores. The changes ensure that thumbnails are consistently and reliably created across both workflows.

We have addressed the issue where thumbnails were missing when:

• An eCommerce store was created from a blank template
• A new webinar was created

• The thumbnail generation process has been refined to improve its reliability and consistency across different creation scenarios.
