Vote for a feature request. action controls semantics:
'toggle' (default) flips the vote, 'subscribe' is idempotent add,
'unsubscribe' is idempotent remove. ticketId is the ticket id or its
number; only feature requests take votes. Emails are matched
case-insensitively and stored lowercased. The response carries the
request's status (customer-facing label, null when not public),
public flag and shareUrl.
