Queue should display students' preferred name

[andrewj-brown]

Problem
Queue presents regular awkward moments where students in my classes use a preferred name that is different to their legal one. Other tutors, student, and the queue itself do not appear to be aware of this choice, as the queue presents only the primary/legal name.

This affects gender diverse students, students who use an angliscised name, etc.

Solution
UQ offers the ability for students to set a preferred name via SInet. The queue should display the preferred name for students in the queue, which would result in tutors, other students, etc. seeing the preferred name on the board, rather than the legal one.

Alternatives
I haven't thought of any good ones. Queue has to have some identifying field for students; it is much better to have names than "ticket numbers" or other non-personal identifiers. If we accept this, and there has to be a personal identifier... it's much better to use the preferred one.

The only situation where preferred names may present issues is where students are expected to present ID cards (e.g. for in-person demos that are organised via the queue), but this can be resolved in-course; tutors should just be aware that the names might differ, and should use student numbers to cross-check students against marking lists.

Context
I don't know how/where the name data comes from. If it comes only from enrolment data uploaded by a coordinator, this change not be possible. Ideally, the data is just pulled from SInet and should therefore be fairly changeable.

I've investigated this further and now believe it might be out of Queue's control - the KVD documentation for zones* suggests that the "name" field should be the preferred name already.

Will follow up on that and return here later.

EDIT: Queue appears to be performing incorrect caching behaviour of the preferred names. See linked PR for more information.
