VSN-1958 : Refactor(anomaly-config): simplify vehicle anomaly configuration structure and API

• Refactored vehicle anomaly configuration to use a simplified, map-based structure instead of individual configurations per anomaly type
• Consolidated vehicle anomaly config API from 9 endpoints down to 3 (GET by vehicle, GET by UUID, PUT to create/update)
• Migrated from storing separate fields (anomalyType, configKey, enabled, scheduleDetails, etc.) to a single JSON configurations map
• Added new endpoint for retrieving paginated vehicle list with filters
