* Fixed a bug where `prompt` and `negativePrompt` were both being
added directly to HTML without escaping them. Given prompts are
allowed to have HTML characters (e.g. `<lora:something:0.75>`), by
forgetting to escape them some tags were missing in the metadata
views for example images using those characters.
- 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.
