feat(admin): Add version API endpoint and refactor admin/moderation layouts

- Create new `/api/version` endpoint to retrieve git commit count and hash information
- Simplify admin page layout by removing unnecessary nested divs and card wrapper
- Refactor moderation page tab navigation with improved button styling using btn-sm and btn-primary classes
- Consolidate padding and styling in moderation page for cleaner component structure
- Add word-break and overflow-wrap styles to report content display for better text handling
- Improve responsive design by adding minWidth: 0 to flex containers in report cards
- Streamline conditional rendering in admin settings to reduce DOM nesting depth
