Sanitises a display name: collapses whitespace, strips control characters and the characters that
could shape markup or a header (<, >, "), and caps the length. The result is for display
only — it is still HTML-escaped wherever it is rendered.
Parameters
raw: string
Returns string
the cleaned name, or null when nothing usable is left
