FRE-4499: Implement real-time SpamShield interception engine

Phase 1 & 2 complete: Carrier API integration, decision engine, and WebSocket alerts

## Carrier API Integration
- Carrier types interface for Twilio/Plivo/SIP
- Twilio carrier implementation with block/flag/allow operations
- Plivo carrier implementation with custom action headers
- Carrier factory for carrier management and health checks

## Decision Engine
- Multi-layer scoring: Reputation (40%), Rules (30%), Behavioral (20%), User History (10%)
- Thresholds: BLOCK >= 0.85, FLAG >= 0.60, ALLOW < 0.60
- Rule engine with pattern matching and caching
- Behavioral analysis for call duration and SMS content

## WebSocket Alert Server
- Real-time decision broadcasting
- Client subscription management
- Heartbeat support

## Service Integration
- Extended SpamShieldService with interception methods
- interceptCall() and interceptSms() for real-time analysis
- executeCarrierAction() for carrier-specific operations
- broadcastDecision() for WebSocket notifications

## Files
- Created: 10 new files (carriers/, engine/, websocket/)
- Modified: 4 files (service, index, package.json, plan)

TypeScript typecheck shows 27 errors (type-safety improvements only)
