🟡send_push(user_id, user_ids, topic, all, title, ...)
Send a push notification to one user (user_id), a list (user_ids, up to 1,000), a topic, or everyone (all: true). Give exactly one target. A push to one user, sent now, answers with its result at once; others answer with status sending or scheduled. With a test key (sk_test_) only test devices receive it.
