feat: hide label on hidden input type

[Benehiko]

Related Issue or Design Document

Hide the label if the input field is of a hidden type.

In Ory Kratos one-time code flow we have access to the input fields after the initial submit (step 2 of 3). Kratos will send back the nodes as hidden fields which will still have their labels attached.

Also fixes the resend button. The auth-code-section component did not render the hidden input field to specify the method when submitting the resend button. This is now fixed and the test assertions fixed.
