Create Success Rate Config

• defaultBucketSize — how many of the most recent transactions per gateway the score is computed over. A small bucket reacts fast to a gateway going down but is noisier; a large bucket is stable but slower to notice change. This is a sliding window: new outcomes push old ones out, so the score always reflects recent behaviour.
• defaultHedgingPercent — the share of traffic deliberately explored away from the current best gateway. Without exploration the engine would starve non-leading gateways of traffic and never learn that they have recovered; hedging keeps every candidate’s score fresh. (This is the same dial Autopilot tunes automatically.)
• defaultLatencyThreshold — optional latency ceiling used when penalising slow gateways.
