Patch: Client default_organization import issue on terraform generate

[duedares-rvj]

🔧 Changes

1. Updated the default_organization schema by relaxing the ConflictsWith and RequiredWith parameters, allowing constraints to be handled independently.
2. Replaced the usage of a nullable struct with an additional API call to set default_organization to nil.
