[Rezwanul-Haque]

Feature Request

Epic: User Engagement & Transparency

Describe the feature you'd like:
🎯 Summary:
As a logged-in user, I want to see a dashboard report that displays key blood donation statistics so that I feel confident that the platform is active and impactful, encouraging future participation and trust in the app.

📝 Description:
We want to add a new section within the app — possibly a new tab or part of the "My Activity" page — that shows platform-wide blood donation stats like:

• Total donation requests

• Completed donations

• Pending requests

• Most donated blood groups

• Top locations

• Success rate

This helps in building trust, encouraging re-use, and demonstrating platform impact.

Is your feature request related to a problem? Please describe:
No

Proposed Solution:
Backend: Create endpoint GET /api/impacts-summary

Backend: Aggregate data from donation requests table

Frontend: Create "Impact Report" screen with summary boxes

Frontend: Add visualizations (optional: use Chart.js or Recharts)

Add loading state + fallback if data fetch fails

Unit test and integrate with production DB
