- Backend: Added confidence_high/moderate/low/total_output_rows to
JobListResponse, computed via a batch query joining output_rows
- Frontend JobCard: Shows a stacked progress bar with green/amber/red
segments and counts for High/Moderate/Low confidence tiers
- Frontend StepConfigure: Auto-selects Amazon as default client when
creating a new job (falls back to first client if Amazon not found)
