fix: resolve all 7 type errors that broke the production build

next build runs 'Linting and checking validity of types' and fails on
the first type error, so the Coolify image build died at
app/api/cipc/search/route.ts:640. These errors were pre-existing but
only surface on next build (npm run dev does not type check).

- cipc/search/route.ts: coerce spawnSync stdout/stderr with toString();
  result is typed as the un-overloaded return, so they are string|Buffer
- group-report pdf+email: use fetchCollection<YsterbaardGroup> instead of
  an invalid cast; normalise description null -> undefined for ReportData
- CipcExplorer (cipc + cipc-2): split the state ternary into two returns;
  the RowState union correlates state with differs, so 'diff' | 'match'
  matched neither variant
- ComplianceTreeGrid: ar_non_compliance_date is optional; the API omits it
  and this component never reads it

Verified: tsc --noEmit 0 errors, next build exit 0, standalone output ok.
