Fix full-screen mode usability issues and enhance reading experience

Full-Screen Mode Improvements:
- Fix navigation controls background transparency issue in reading mode
- Add semi-transparent backgrounds with backdrop blur for better visibility
- Implement theme-aware colors matching user's selected theme (light/dark/sepia)
- Add subtle borders for better visual definition without distraction

Verse Action Buttons Enhancement:
- Enable bookmark, copy, and chat buttons in full-screen reading mode
- Remove reading mode restriction that was hiding essential verse-level functionality
- Add theme-aware hover effects for better integration in reading mode
- Implement adaptive opacity (0.2 in reading mode, 0.3 in normal mode)
- Smooth hover transitions that reveal buttons when needed

Smart Chat Integration:
- Automatically exit full-screen mode when chat icon is clicked from reading mode
- Add smooth transition timing to allow exit animation to complete
- Preserve verse context and pre-filled AI messages through mode transitions
- Prevent chat from opening hidden behind full-screen overlay
- Maintain authentication flow and redirect logic

User Experience Enhancements:
- Professional navigation bar with backdrop blur effect (modern glass morphism)
- Non-intrusive verse actions that don't distract from reading
- Intelligent behavior that adapts based on current reading mode
- Seamless transition from immersive reading to AI conversations
- Consistent visual experience across all themes and modes

Technical Implementation:
- Theme-aware styling for dark, light, and sepia modes
- CSS backdrop-filter for modern blur effects
- Smart timing with setTimeout for smooth transitions
- Preserved functionality while improving visual integration
- Enhanced hover states with custom theme-matching colors
