root a42ef16113 oanda: retry once on transient 401/5xx/network faults in candle fetch ...

The practice API rejects ~15-20 requests/day with a spurious 401
"Insufficient authorization" while the same token succeeds on adjacent
requests; each one silently cost a full scan cycle on that timeframe.
One retry after RETRY_DELAY_S (2 s) absorbs these plus transient
5xx/network faults. Real credential failures fail both attempts and
raise as before; other 4xx (bad request, 429) are never retried.

Tests: transient-401 recovery, persistent-401 raise, 400 not retried.
