feat: add user contributions summary

[Jampaa]

User Contributions Feature – Summary

Implemented a new User Contributions page that displays group-level annotator and reviewer totals using:

GET /contributions/{group_id}/summary

The page shows:

Overall totals (all-time)
Filtered totals (within a selected date range)

in the format:

overall (filtered)

Example: 40 (17).

Key Logic
Default filter uses a rolling 30-day inclusive range.
end = today
start = end - 29 days
Both dates are inclusive, so the range always contains exactly 30 days.
Data Fetching
Overall and filtered summaries are fetched in parallel using Promise.all().
Results are cached with TanStack Query using groupId + date range as the cache key.
User Experience
Non-admin users automatically see their group’s contributions for the last 30 days.
Admins can view all groups and apply custom date filters per group.
Additional Updates
Added route: /admin/user-contributions
Added sidebar navigation item
Added English and Tibetan translations
