[UI] Fix responsive layout issue on iPad Air viewport

Description

The Meshery page has a responsive layout issue when viewed at the iPad Air viewport (820 × 1180).

At this viewport width, the testimonial section does not adapt correctly to the available space. The testimonial text and the author's image/name become cramped, resulting in an inconsistent/broken layout.

Since iPad Air uses a relatively wide tablet viewport, the page should provide a properly responsive layout at this breakpoint.

Expected Behavior

The Meshery page should remain properly responsive and visually aligned on iPad Air (820 × 1180).

The testimonial content, author image, divider, and author information should have sufficient spacing and should not become compressed or overlap.

Screenshots

The issue can be reproduced using Chrome DevTools with the iPad Air device preset:

Viewport:
820 × 1180

Environment:

• Browser: Google Chrome
• Device/Viewport: iPad Air (820 × 1180)
