Description:

Build the complete admin panel for managing all content types (Members, Research Areas, Collaborators, and Photos). Implement full CRUD operations with intuitive UI components including drag-sort lists, image uploaders, Markdown editors, and form validation. This excludes the automated publication crawler system which will be implemented separately.

Tasks:

• Implement Members management (create/edit/delete, image upload, drag-sort, category assignment)
• Implement Research Areas management (tree editor, Markdown editor with preview, DOI association, drag-sort hierarchy)
• Implement Collaborators management (CRUD with map picker for coordinates)
• Implement Group Photos management (upload by year, image optimization)
• Create reusable admin components (DataTable, DragSortList, ImageUploader, MarkdownEditor, MapPicker)
• Add API routes for all CRUD operations with proper validation
• Implement form validation and error handling across all admin pages
