_do_reconnect() succeeded but never called
YuanbaoAdapter.set_active(adapter), leaving get_active()
permanently returning None after any WS disconnect/reconnect
cycle. This caused cron delivery to silently fail because
_send_yuanbao() checks get_active_adapter() and gives up
immediately when it returns None.
Fix: call set_active(adapter) after successful reconnect,
matching the pattern in connect().
Fixes#58363
