Implement Certificate and Revocation Analytics Dashboard

[lahirujayathilake]

Create a monitoring dashboard that visualizes

• Active certificates per client
• Revocation history
• CA rotations
• Failed signing attempts

Integrate with Prometheus metrics and Custos Portal UI for operator visibility.

Hi @lahirujayathilake ,

I’ve been working on a frontend prototype for the SSH Certificate Analytics Dashboard.

Instead of starting directly inside the repo, I built a production-style prototype to validate:

• Role-based UI (Admin vs Operator)
• Certificate analytics dashboard
• Revocation workflows
• CA key visibility
• React Query + API abstraction layer

Code:

I’d love feedback on:

1. Whether this aligns with Custos UI direction
2. How this should be integrated (separate module vs existing UI)
3. API expectations for certificate analytics

If this direction looks good, I can start converting this into a proper PR aligned with the repo structure.
