fix: resolve unresponsive Go Back Home button on 404 page in production

[Rohanpawar9921]

PR Fixes:

• Fixed unresponsive "Go Back Home" button on 404 page in production environments
• Resolved hydration mismatch issues caused by complex Button + asChild component chain
• Replaced Radix UI Button component with direct Link to eliminate client-server rendering inconsistencies
• Maintained identical visual styling and user experience while improving reliability

Root Cause: The original implementation used <Button asChild><Link href="/"> which created a complex component chain (Button → Slot → Link) that caused hydration mismatches in production. The server-rendered HTML differed from client-side React rendering, preventing proper event handler attachment.

Solution: Simplified the component structure by using a direct <Link> element with inline button styling classes, eliminating the hydration-prone component composition while preserving the exact same appearance and functionality.

Technical Details:

• Removed dependency on @radix-ui/react-slot for this component
• Applied button variant classes directly to Link component
• Ensured consistent server-side and client-side rendering
• No breaking changes to existing functionality or visual design

Resolves #1868
