Resolves#41996
Some IdPs push SCIM PATCH operations that bundle `department` with other
RFC 7643 §4.3 enterprise attributes that Fleet does not store. Before
this change the SCIM library rejected those payloads with a 400 because
the schema only declared 'department'.
An environment variable was added (FLEET_DEBUG_SCIM_PAYLOADS) for aiding
in further debugging this if the issue persist.
