Web v2: support altering incorrect password on catalog edit page although the secret is hidden in API response

Start at the Web v2 catalog edit page and inspect how its form handles the password field when the API response hides the secret. Confirm the current incorrect-password flow, then verify that a user can alter the password and save the catalog successfully without exposing the returned secret.
