Restart the Gateway when its historical data farm stops serving

On 2026-10-12 the Gateway answered account requests but every bar request
timed out from 09:50 to 10:24 ET: make gateway reported OK, so the Gateway was
never restarted, and six retries 5 minutes apart gave up after 35 minutes. The
data came back only with the Gateway's daily restart.

ibkr-quant gateway --history also requires SPY daily bars within 30 s; the
trade job's ExecStartPre passes it, so ensure-gateway.sh restarts a Gateway
whose data farm is down. The trade job now retries every 10 minutes until
about 15:30 ET (34 starts in 6 h) instead of giving up after 35 minutes.
