✨ Enhance Codex UI components and implement ChatHeader auto-hide functionality

[Copilot]

This PR implements comprehensive UI improvements for the Codex main page and adds auto-hide functionality to the ChatHeader component in the message interface.

🎨 UI Improvements for Codex Components

RoadmapGridWithMission Enhancements

• Enhanced gradient backgrounds with improved theme consistency using from-slate-900/95 via-slate-800/95 to-slate-900/95
• Interactive hover effects with smooth color transitions and group hover states
• Improved mission panels with enhanced visual hierarchy and better spacing
• Animated status indicators with pulsing effects and enhanced shadows

RoadmapGrid Component Polish

• Mission cards redesign with enhanced gradients, backdrop blur, and subtle glow effects
• Hover animations including scale transforms (hover:scale-103) and vertical translation
• Staggered entrance animations using Framer Motion for better user experience
• Enhanced modal design with improved gradients, rounded corners, and better content layout
• Consistent theme integration replacing hardcoded colors with amber/orange palette from globals.css

⚡ ChatHeader Auto-Hide Functionality

Implemented smart auto-hide behavior for the chat header:

// Auto-hide after 5 seconds of inactivity
const resetTimer = () => {
  if (!isHovered && window.scrollY > 50) {
    timerRef.current = setTimeout(() => {
      setIsVisible(false);
    }, 5000);
  }
};

// Show header on upward scroll
const handleScroll = () => {
  const scrollingUp = currentScrollY < lastScrollY.current;
  if (scrollingUp || currentScrollY < 50) {
    setIsVisible(true);
    resetTimer();
  }
};

Key Features:

• 5-second auto-hide timer that activates when user stops interacting
• Scroll detection to show header immediately when scrolling up
• Hover protection prevents auto-hide when user is interacting with header
• Smooth transitions with duration-500 ease-in-out for professional feel
• Enhanced styling with improved colors, hover effects, and visual feedback

🔧 Technical Improvements

• Performance optimized with proper cleanup of event listeners and timers
• Accessibility enhanced with better keyboard navigation and visual feedback
• Responsive design maintained with mobile-first approach and improved spacing
• Code quality following minimal changes principle with no breaking modifications
• Theme consistency using CSS variables from globals.css throughout

📱 Visual Enhancements

• Consistent amber/orange gradient palette across all components
• Enhanced shadow effects and backdrop blur for modern glass-morphism look
• Improved button states with scale feedback (active:scale-95)
• Better visual hierarchy with proper typography and spacing
• Subtle animations that enhance UX without being distracting

All changes maintain full responsiveness and accessibility while providing a more polished and interactive user experience.
