feat: Refactor LoraModal into modular components

- Added ShowcaseView.js for rendering LoRA model showcase content with NSFW filtering and lazy loading.
- Introduced TriggerWords.js to manage trigger words, including editing, adding, and saving functionality.
- Created index.js as the main entry point for the LoraModal, integrating all components and functionalities.
- Implemented utils.js for utility functions such as file size formatting and tag rendering.
- Enhanced user experience with editable fields, tooltips, and improved event handling for trigger words and presets.
