feat(web): add animations to landing page

[rajanarahul93]

Description

This PR introduces subtle animations to the landing page to improve user engagement. It adds a staggered entry animation to the hero section text and a hover/press effect to all standard buttons, making the UI feel more dynamic and responsive.

Changes Made

• Added a scale transform on hover/press to the shared button component.
• Wrapped the button animation in the motion-safe variant to respect users' prefers-reduced-motion accessibility settings.
• Implemented a staggered fade-in and slide-up effect for the hero section on the landing page using framer-motion.

Checklist

• I have tested my changes locally.
• I have updated the documentation (if applicable).
• I have added/updated unit tests (if applicable).
• My code follows the project's coding standards.
• My changes do not introduce new warnings or errors.

Additional Context

The button animation was updated to include the motion-safe variant based on an accessibility review. This ensures that the animations are disabled for users who have requested reduced motion in their system settings.
