Replace hardcoded pixel values with unit variables in key components:
- GalleryExtended, MediaDetailsModal, UrlEmbedExtended
- EnhancedComposer, UniverseCard, NavDropdown, Button
Key replacements:
- Spacing: 1px→$unit-1px, 8px→$unit, 16px→$unit-2x, etc.
- Font sizes: Use semantic $font-size-* variables
- Border radius: Use $corner-radius-* variables
Added missing common pixel value variables for consistency.
