Add item-level history badge and animations

- Show a dynamic field-count badge next to All Fields (Detailed View) in the moderation queue
- Animate collapsible sections with smooth transitions for expand/collapse
- Pass fieldCount to DetailedViewCollapsible and render count alongside header; add animation utility in DetailedViewCollapsible.tsx
- Ensure SubmissionItemsList passes item data to calculate field counts and display badges accordingly
