Refactor service name code to reduce duplication

This makes the code shareable between:
- the broadcast tour pages
- the broadcast settings platform admin page
- the regular service navigation

On the training mode tour pages we don’t want to confuse people with the
organisation name or _Switch service_ links, so those are omitted and
the code is therefore slightly different.
