feat: Add content-type specific card styles

PostCardNew now renders different styles based on content_type:
- camera/live/stream: TV-style with red pulsing LIVE badge
- video: Card with centered play button overlay
- photo/picture/image: Polaroid white-frame style
- default: Standard gallery image
