Fix: Correct exporterExcel method call parameters

The exporterExcel method signature requires 11 parameters but was being
called with only 3. This caused a compilation error during deployment.

Fixed by providing all required parameters:
- format, associationId, statut, type
- dateAdhesionDebut, dateAdhesionFin
- colonnesExport
- inclureHeaders, formaterDates, inclureStatistiques
- motDePasse

Most parameters are set to null or default values for now.
