Fix mobile featured products to display two columns

[CySSoO]

Motivation

• On narrow screens product miniatures in .ever-featured-products could be rendered one per row when theme CSS overrides Bootstrap, so enforce a two-column layout as a fallback for mobile.

Description

• Add a mobile media query in views/css/everblock.css that sets .ever-featured-products .products.row > * to flex: 0 0 50% and max-width: 50% for screens below 768px.
• The change is scoped to the .ever-featured-products block and does not modify tablet or desktop behavior.

Testing

• Ran git status --short && git log -1 --oneline which succeeded and shows the change committed.
• Performed the git commit operation which completed successfully and recorded the patch.
• Tried a Playwright screenshot run against http://localhost which failed with ERR_EMPTY_RESPONSE because no local server was available to render the page.
