UI: Admin Dashboard for App Metrics

# 💡 Summary #

Create an admin application dashboard that reports application metrics for system admins. The dashboard metrics should include:
- **User Data Metrics**: Display key metrics related to user activity, such as sign-ups, logins, and active users.
- **Organization Data Metrics**: Show relevant data about organizations, such as the number of organizations, their size, and engagement levels.
- **Scans Metrics**: Present information related to security scans, performance, frequency, and/or any other relevant scans conducted within the application.

Secondarily all reportable data should allow for "csv, excel" exports.

## Motivation and context ##

This is invaluable tool to manage service reports.

## Implementation notes ##

[ ] Add total number of organizations.
[ ] Add Distribution of organization sizes (small, medium, large).
[ ] Add Metrics related to organization activity (e.g., number of projects, collaboration frequency).
[ ] Add Performance scan metrics (e.g., response time, resource utilization).

## Acceptance criteria ##
- [ ] Document all end-point changes
- [ ] Demonstrate a Response Design
- [ ] Include Screenshots Of Updated Views
- [ ] Commit to Staging
- [ ] Create Functional Tests

No files, tests, or entry points are named. Start by gathering the desired metrics from stakeholders and creating the wireframe or proposal; define the user, organization, scan, and CSV/Excel export scope. Done means documented endpoint changes, a response design, screenshots, staging deployment, and functional tests.
