feat: implement hybrid database architecture and frontend encryption
- Add PostgreSQL + SQLite hybrid database support with automatic switching - Implement frontend AES-GCM + RSA-OAEP encryption for sensitive data - Add comprehensive DatabaseInterface with all required methods - Fix compilation issues with interface consistency - Update all database method signatures to use DatabaseInterface - Add missing UpdateTraderInitialBalance method to PostgreSQL implementation - Integrate RSA public key distribution via /api/config endpoint - Add frontend crypto service with proper error handling - Support graceful degradation between encrypted and plaintext transmission - Add directory creation for RSA keys and PEM parsing fixes - Test both SQLite and PostgreSQL modes successfully 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: tinkle-community <tinklefund@gmail.com>
