feat: Add Redis caching, security validation, and Docker containerization 

REDIS CACHING:
- Connection pooling with max 50 connections
- Namespace-based cache keys (market, ai, signal, etc)
- TTL management per data type
- Batch operations and pattern deletion
- Distributed locking support
- LRU eviction policy

SECURITY VALIDATION:
- SQL injection prevention
- XSS prevention with HTML entity encoding
- SSRF prevention in webhooks
- Rate limiting with time windows
- HMAC-SHA256 request signing
- API key validation and secure generation
- Pydantic validation for all inputs

DOCKER CONTAINERIZATION:
- Multi-stage Dockerfile for optimization
- Complete production stack with docker-compose
- Services: PostgreSQL/TimescaleDB, Redis, Prometheus, Grafana
- Development environment with hot reload
- Health checks and resource limits
- Non-root user execution for security
- Persistent volumes and backups

System is now production-ready with institutional-grade infrastructure.
