1. Compliance CSV/PDF: Replace non-existent pd.total_packages with
jsonb_array_length(pd.installed_packages) and pd.pending_patches
with pd.patch_count. Fix GROUP BY to match new columns.
2. Vulnerability CSV/PDF: Replace non-existent pd.cve_data with
jsonb_array_elements on pd.available_patches JSONB, extracting
cve_ids via nested lateral join. Replace pd.updated_at with
pd.polled_at (actual column name).
3. TypeScript: Remove duplicate PollingConfig interface declaration
in frontend/src/types/index.ts.
4. ReportsPage: Replace Group ID text field with Select dropdown
populated from GET /api/v1/groups, showing group names instead
of requiring UUID input.
5. PDF charts: Increase embed_image scale from 0.18 to 0.28 for
better visibility on A4 landscape pages.
6. Vulnerability CSV: Remove invalid (no data) comment row on
query failure; return header-only CSV instead to maintain valid
CSV format.
