What inputs does update_signal accept?

alert_id (string, required): The signal's `id` from `list_signals` / `create_signal`. name (string, optional): New human-readable label. condition (object, optional): New condition — the same discriminated union `create_signal` takes. Replaces the stored condition entirely. channels (array, optional): New delivery list (up to 4, each a distinct type+target). Replaces the stored list entirely; the first entry becomes `channel`.
