Enhance the Signature Validation feature on the Token Detail screen to do full JWT validation

[rcbjBlueMars]

Review the JWT validation procedure outlined in [1]. When a JWT is acting as an OIDC ID Token, the validation process outlined in [2] is also relevant. Each of these details should be checked and the result of that check displayed in a results field. A JWT validation library could be used to accomplish this, but only if the library exposes the individual steps, rather than wrapping the whole validation into a single operation.
