feat: implement absolute positioning for slide editor with viewport-aware layout

## Major Improvements:

### Absolute Positioning System
- Implemented fixed positioning for slide editor to break out of DOM flow
- Editor uses full viewport (top: 80px; left: 0; right: 0; bottom: 0)
- Fixed header at top with z-index layering for proper overlap
- Background overlay to separate from underlying content

### Viewport-Optimized Layout
- True 50/50 split using full available viewport width
- Height calculations based on actual viewport (100vh) not container constraints
- Responsive top positioning (80px desktop, 60px tablet, 50px mobile)
- No scrolling issues - content always fits within viewport boundaries

### Enhanced Live Preview
- Applied presentation aspect ratio classes to preview container
- Dynamic aspect ratio detection (16:9, 4:3, 16:10)
- Viewport-aware sizing with proper aspect ratio preservation
- Added aspect ratio indicator in preview meta information

### Improved User Experience
- Compact header design with reduced padding and font sizes
- Internal scrolling for content fields while keeping actions visible
- Better space utilization with reduced margins and gaps
- Consistent behavior across all screen sizes and orientations

### Technical Enhancements
- Z-index management for proper layering (header: 20, content: 10)
- Flexbox structure for optimal space distribution
- Overflow handling for different content types
- Mobile-responsive design with appropriate scaling
