Implement dynamic device profile system using LibreNMS YAML definitions: - Create 7 database tables for device profiles, detection rules, sensors, processors, memory pools - Add DeviceProfiles context module with profile matching logic - Add YAML importer to parse LibreNMS os_detection and os_discovery files - Add mix task for importing profiles from LibreNMS repository - Create Dynamic profile module to interpret database definitions at runtime - Update discovery.ex to check database profiles before hard-coded modules - Fix Redis PubSub configuration to support unnamed nodes for Mix tasks Imported 5 Ubiquiti/Cambium profiles: epmp, airos-af, airos-af-ltu, airos-af60, unifi The system now supports 671+ device profiles from LibreNMS without requiring code changes for each device type.
