Add an option to display the pronoun badges from https://pr.alejo.io/ (also available as an FFZ add-on) in the chat render.

The pronouns for a given user can be looked up at e.g. https://pronouns.alejo.io/api/users/fenhl and the mapping from internal IDs to human-readable text is at https://pronouns.alejo.io/api/pronouns.
