Passphrase credentials should correctly grey out disallowed actions.

Summary: Fixes T7493, Credential actions in Passphrase should correclty appear greyed out if clicking them will result in a "You Shall Not Pass" dialog.

Test Plan: Create a credential that is visible to everyone but editable by one, login as a user incapable of editing it, navigate to the credential view, all actions should be greyed out, and all actions should open a "You Shall Not Pass" dialog.
