Fix follow-up requested consent label in activity log

The raw enum value "follow_up_requested" was interpolated directly into the timeline title, producing "Consent follow_up_requested". Use Consent.human_enum_name to resolve the I18n translation instead, which yields the correct human-readable label for all response types ("Consent given", "Consent refused",  "Follow-up requested").
