fix: trigger card animation automatically on mobile viewport entry (#8093)

[MAYANKSHARMA01010]

Description

This PR fixes #8093.

On the Operate Your Infrastructure page, feature card animations were previously triggered solely by mouse hover events (onMouseOver), meaning they never fired during scrolling on mobile or touch devices.

Changes Made:

• Added an IntersectionObserver (with SSR safety checks) to observe each Kanvas feature card and trigger the secondary graphics and speedometer animations automatically when cards enter the viewport on mobile and small screens (<= 992px or touch devices).
• Preserved existing desktop hover behavior, including the .darken contrast dimming on non-hovered sibling cards.
• Left the original card UI, layout, styling, and dimensions completely intact.

Summary by CodeRabbit

• Improvements
  • On small screens and devices with coarse pointers, feature cards activate their animations when they enter the viewport and stop when they leave.
  • Hover interactions remain available, so cards can still respond to hover where supported.
  • Cards without documentation links remain unlinked.

📝 Walkthrough

Walkthrough

Feature cards now activate their animated images and service meter when they enter the viewport on small screens. Hover activation remains available. The component and its default export use the corrected name.

- Line 148: Update the `mediaQuery` in the `isSmallScreen` activation logic to
also match `(any-pointer: coarse)`, so touch-capable devices activate the cards
even when the viewport is wider than 992px and the primary pointer supports
hover. Preserve the existing width and hover conditions.
