refactor: replace Hero CSS animations with Framer Motion .

[Hell1213]

Replaced CSS keyframe animations in the Hero section with Framer Motion. Removed 62 lines of custom CSS including keyframes and media queries from index.css. Implemented the same color-shifting glow effect using Framer Motion's animate prop with responsive sizing via Tailwind classes. Visual appearance remains identical.

Fixes: #450

Checklist

• Ran npx prettier --write . (for formatting)
• Ran gofmt -w . (for Go backend) - N/A (frontend only)
• Ran npm test (for JS/TS testing)
• Added unit tests, if applicable - Updated snapshot test
• Verified all tests pass - 670 tests passing
• Updated documentation, if needed - N/A

Additional Notes
This change consolidates animation logic by using the existing Framer Motion dependency instead of maintaining separate CSS animations. The glow effect behind the hero cards animates between pink and blue colors with the same timing and visual result as before.

@Hell1213 this looks great! I think you forgot about the Homepage though. Moreover can you make this a separate component? maybe in utils, for common access, and better testing.
