Allow selection of disclosure items

Fix preview screen

• Corruption of the data credentialData.json used to display the preview of the CredentialDetail screen has been fixed.
• Added tests for ModelData.swift to ensure resource data is continually maintained.

Allow selection of disclosure items

• By interpreting the optional property in the constraints of the Input Descriptor, we have made it possible for users to decide whether or not to send claims that are not required to be disclosed.
  • optional property is defined in 5.1.1 Input Descriptor Object
• Regarding the UI, a toggle button has been added to indicate that selective disclosure is possible. (When the toggle is on, it will be sent. When it is off, it will not be sent.)
• A new data structure DisclosureWithOptionality has been added to hold the results of the toggle.
  • The existing data structure Disclosure is directly linked to SD-JWT, so a new data structure has been added.
  • The properties isSubmit and optional of DisclosureWithOptionality have the following meanings:

value of isSubmit	value of optional	semantics
false	false	This is an unnecessary claim for the verifier and will not be sent.
false	true	This is an optional claim, and the user does not wish to make any additional disclosures.
true	false	This is a required claim and should be sent.
true	true	This is an optional claim, but is sent at the user's discretion.
