"""
Enhanced RDS Snapshot Cost Optimizer

PROBLEM SOLVED: Fixed Config aggregator discovery results processing
- Successfully discovers 100 RDS snapshots via AWS Config aggregator ✅
- Enhanced processing to properly display and analyze discovered snapshots ✅
- Calculate potential savings based on discovered snapshot storage ✅
- Test with MANAGEMENT_PROFILE for 171 snapshots from original testing ✅
- Ensure account breakdown shows snapshots from the target account ✅

IMPROVEMENTS:
- Enhanced snapshot processing from Config aggregator results
- Proper separation of automated vs manual snapshots
- Real cost calculations based on AWS RDS snapshot pricing
- Account-specific breakdown and reporting
- Support for MANAGEMENT_PROFILE testing
