Fix reduced-motion accessibility across DevTrack motion surfaces

[DiyaRathod-16]

Hi @Priyanshu-byte-coder
Summary:
This PR fixes DevTrack’s reduced-motion accessibility behavior so the app respects users who set prefers-reduced-motion: reduce in their OS or browser. The change reduces or disables non-essential movement across the main motion surfaces in the app, including the landing ticker, entrance animations, counters, and hover transforms.

What changed:

Added a global reduced-motion media query in globals.css to suppress animation and transition motion site-wide for users who prefer reduced motion.
Disabled the landing ticker animation so the scrolling commit strip no longer moves for reduced-motion users.
Forced fade-up content to render immediately so content is never left hidden behind an entrance animation.
Updated the landing-page counter in LandingPage.tsx so numeric animations resolve instantly when reduced motion is enabled.
Guarded the remaining hover scale behavior in DeveloperPersona.tsx so the card motion stays motion-safe.
Kept the existing motion-aware hook behavior aligned with the accessibility preference instead of relying on CSS alone.
Why this matters:

This addresses the motion-triggering behavior reported in the issue and improves accessibility for users with vestibular sensitivity, migraines, or motion sickness.
It follows WCAG 2.2 guidance for respecting prefers-reduced-motion and avoids forcing non-essential animation on users who explicitly opted out.
Validation:

Verified the updated files for errors after the changes.
Confirmed the diyacommits branch is pushed to the forked repository.
