Add a convenience GET /api/v1/faults endpoint

[mfaferek93]

Summary

Add a convenience GET /api/v1/faults endpoint that returns all faults across the system without requiring iteration over individual components.

Currently, to get all faults, clients must:

1. GET /api/v1/components to list all components
2. GET /api/v1/components/{id}/faults for each component

This is inefficient for dashboards and monitoring tools that need a complete system health view.

---

Proposed solution (optional)

Add GET /api/v1/faults endpoint that:

• Returns all faults from all sources in a single request
• Supports ?status= query parameter for filtering (pending, confirmed, cleared, all)
• Default returns pending + confirmed faults (active issues)

Response structure:

{
  "faults": [...],
  "count": 5
}

---

Additional context (optional)

• This is a convenience API extension beyond the per-component fault endpoints
• Primary use case: FaultsPanel component in Web UI
