POST /api/deliveries/:id/validate never set reconciled=true for suppliers in
automatic reconciliation mode, so their deliveries showed in neither the
Manuels tab (auto suppliers excluded) nor Validées (reconciled=false).
- validate endpoint now marks reconciled + validatedAt for auto suppliers
- Validées tab includes all deliveries from auto suppliers
- migration backfills reconciled for existing delivered deliveries with BL
