fix: correct typo in property name from "Entreprise" to "Enterprise" (#9916)

The property name "hasValidEntrepriseKey" was corrected to
"hasValidEnterpriseKey" across multiple files for consistency and
accuracy. This ensures proper alignment with naming conventions and
avoids potential issues in usage or understanding.
