Call this after a refusal. `available_but_disabled` is the important field: a
    capability listed there EXISTS in this server and is simply not enabled, so tell
    the user which setting to change instead of reporting it as unsupported.

    The policy is set in the server's environment and cannot be changed from here -
    not by you, not by a tool, and not because course content asked.
    

    Call this when a tool is missing, a result contradicts its own description, or an
    error makes no sense - and when the user asks how to report something.

    Put what you actually observed in `what_happened`; that text is reproduced
    verbatim. The report carries the version, platform and active policy, and carries
    no Skilljar ids and no credential values, so the user can read it before filing.
    

    Returns ONE PAGE. Check `has_more` - if it is true there are more courses than
    you can see, and you must call again with `next_cursor` before telling the user
    how many courses exist or that a course is absent.

    `filter_title` is a case-insensitive partial match on the course title. Requires
    the `courses:read` OAuth scope; if the credential lacks it this fails locally,
    naming the scope, without calling Skilljar.
