FidoRegistrationCallback
FIDO2 registration callback for ForgeRock Journey workflows.
This callback handles the FIDO2 credential registration process within a Journey workflow. It processes credential creation options from the server, performs the registration using the device's FIDO2 capabilities, and formats the response for the Journey framework.
The callback supports both legacy string-based and modern JSON-based response formats depending on the server capabilities. It also supports optional device naming for better credential management.
