Circuit-breaker configuration & observability endpoints

[DevMuhdishaq]

Description
A volume-threshold circuit breaker is referenced but its thresholds and current state should be admin-configurable and externally observable for the emergency-recovery workflow.

Direction

• In risk_management/alerts, expose set_circuit_breaker_threshold(window_secs, max_volume) (admin) and get_circuit_breaker_status() -> {tripped, current_volume, threshold, window}.
• Auto-trip pauses trading and emits a CircuitBreakerTripped alert; add admin reset_circuit_breaker.
• Reuse the pause mechanism from Issue ## Issue 1 — Initialize Soroban Rust Project #1.

Acceptance criteria

• Crossing the configured volume threshold within the window trips the breaker and pauses swaps.
• get_circuit_breaker_status reports accurate live values.
• reset_circuit_breaker (admin only) restores trading.
• A CircuitBreakerTripped event/alert is emitted on trip.
• Tests simulate volume accumulation across ledgers to trip and reset.
