Description

When a user tries to create a new ZNaturalLanguage etc. that they're not authorised to make, there are no warnings show in the editor as they're creating it, and when trying to publish they get only the generic "User does not have permission to edit" message.

Desired behavior/Acceptance criteria

• When showing the error on attempted publication, don't just show the main error message, but also the secondary information about what specifically is not allowed (e.g. "creating a new programming language object").
• When a user is trying to create one of the common restricted types (Z4, Z60, Z61), detect this and show a message as they edit that it is not allowed.
• In both of the above, link to a user-facing documentation page for each type (to create?) for how to get such things created, rather than stranding the user.

Completion checklist

• Functionality:
  • The solution meets the expected behavior/acceptance criteria described above
  • All the child tasks are closed
  • The issue has been peer reviewed
  • The issue has been merged
• Engineering:
  • There are existing and passing unit/integration tests effectively testing its success and its failure
  • All new classes/methods are covered by unit tests
• Design:
  • Design review of live version in accordance to design standards
• Documentation:
  • All new functions/methods are annotated
• Accessibility:
  • New functionality is compared against the Accessibility guide for developers
  • Accessibility concerns are either address or, if the work is sufficiently large, a new Phabricator ticket is created and linked to this ticket
  • All user facing strings are internationalized
