feat: separate data classification architecture
- Create separate scanner interfaces for storage, system, and docker data - Add dedicated endpoints for metrics and docker images instead of misclassifying as updates - Implement proper database tables for storage metrics and docker images - Fix storage/system metrics appearing incorrectly as package updates - Add scanner types with proper data structures for each subsystem - Update agent handlers to use correct endpoints for each data type
