refactor: Add MediaRenderers, MediaUtils, MetadataPanel, and ShowcaseView components for enhanced media handling in showcase
- Implemented MediaRenderers.js to generate HTML for video and image wrappers, including NSFW handling and media controls. - Created MediaUtils.js for utility functions to manage media loading, lazy loading, and metadata panel interactions. - Developed MetadataPanel.js to generate metadata panels for media items, including prompts and generation parameters. - Introduced ShowcaseView.js to render showcase content, manage media items, and handle file imports with drag-and-drop support.
