Implement Fault Filtering and Lifecycle

[mfaferek93]

Summary

Central filtering in FaultManager: lifecycle (pending → confirmed → cleared) and multi-source aggregation.

---

Proposed solution (optional)

Configuration:

fault_manager:
  filtering:
    confirmation_threshold: 3
    time_window_sec: 30

Logic:

• First report → PENDING
• After N reports (any sources) → CONFIRMED
• Track reporting_sources array
• GetFaults returns CONFIRMED by default

---

Additional context (optional)

• Same fault_code from multiple sources increments shared occurrence_count
• Per-fault overrides via regex patterns
• Add include_pending flag to GetFaults
