refactor: migrate media components to Svelte 5 runes

- Convert all media-related admin components to use $state and $derived
- Update event handlers to use new syntax (onclick instead of on:click)
- Refactor prop destructuring to use interface Props pattern
- Improve type safety and remove legacy reactive statements
- Simplify component logic with Svelte 5 patterns

Components updated:
- AlbumForm: Enhanced validation and state management
- FilePreviewList: Simplified preview rendering
- FileUploadZone: Improved drag-and-drop handling
- MediaDetailsModal: Better metadata display
- MediaGrid: Optimized selection state
- MediaMetadataPanel: Cleaner EXIF data presentation
- MediaUploadModal: Streamlined upload flow
- MediaUsageList: Enhanced usage tracking
- UnifiedMediaModal: Consolidated media management
