🗃️ Add comprehensive SQLAlchemy models for Headscale database
Core Models (based on actual DB schema analysis): - User: Headscale users with relationships - Node: Connected machines with detailed host info - PreAuthKey: Pre-authentication keys with validation - ApiKey: API authentication keys with expiration - Policy: ACL policies (JSON format) Extended Models for FARMQ: - PharmacyInfo: Pharmacy details (name, business number, contact) - MachineSpecs: Hardware specifications per machine - MonitoringData: Real-time monitoring metrics Features: - Complete database relationships and foreign keys - JSON type handling for complex data structures - Timezone-aware datetime handling - Helper methods (is_online, is_expired, is_valid) - Database utility functions - Comprehensive test suite with actual data validation Test Results: ✅ All models working with live Headscale SQLite DB - 1 User: myuser - 1 Node: 0bin-Ubuntu-VM (100.64.0.1) - 1 API Key: 8qRr1IB (valid until Dec 2025) - 1 Pre-auth Key: reusable, valid - Extended tables created and tested successfully Ready for FARMQ pharmacy management system integration. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
