feat: rename syntheticUserId to conversationalUserId [JAR-9965]

Match the CAS-side rename: the forwarded conversation owner id may be a real
cloud user id or a synthetic user id, so 'synthetic' was misleading. Renames
the context field (conversational_user_id) and the FpsProperties key
(conversationalService.conversationalUserId).
