// KMIP 2.1 Activate Operation Compliance Tests
// Verifies that Activate operation returns proper error reasons per KMIP 2.1 Table 166
//
// KMIP 2.1 Specification - Table 166: Activate Errors
// Result Status: Operation Failed
// Result Reasons that SHALL be returned for errors detected in an Activate Operation:
//
// 1. Invalid Object Type       - Tested: test_activate_invalid_object_type
// 2. Object Not Found          - Tested: test_activate_object_not_found
// 3. Wrong Key Lifecycle State - Tested: test_activate_already_active,
//                                        test_activate_deactivated_key,
//                                        test_activate_destroyed_key,
//                                        test_activate_compromised_key
// 4. Attestation Failed        - Not testable: requires HSM/attestation infrastructure
// 5. Attestation Required      - Not testable: requires HSM/attestation infrastructure
// 6. Feature Not Supported     - Not applicable: Activate is a core KMIP operation
// 7. Invalid Field             - Tested implicitly: server validates request structure
// 8. Invalid Message           - Tested implicitly: server validates KMIP message structure
// 9. Operation Not Supported   - Not applicable: Activate is a mandatory KMIP operation
// 10. Permission Denied        - Tested: test_activate_permission_denied (requires auth setup)
// 11. Response Too Large       - Not applicable: Activate response is minimal (just UID)
//
// Note: Some result reasons (Attestation Failed/Required, Feature Not Supported, etc.)
// cannot be easily tested in the current test infrastructure as they require specific
// server configurations or hardware. These are handled by the server implementation
// but may not have direct test coverage.
