Alerts

1 endpoint.

• Alert Trigger — GET /api/v1/alerts/triggers/{id}
  Read back one alert trigger: what it watches (table_filter plus the four narrowing fields netuid, event_kind, account, min_amount_tao -- all nullable, so a trigger that sets none of them matches every event on its table), where it delivers (channel, destination), whether it is active, and its firing record.
