Legacy Update Score

/update-score is retained for compatibility. It does not use the modern /update-gateway-score body — it expects the legacy feedback payload built from full internal transaction objects (txn_detail, txn_card_info). New integrations should use /update-gateway-score, whose request is far simpler.

txn_detail and txn_card_info must each carry a partitionKey key. The value may be null, but omitting the key fails with missing field partitionKey. The id fields are numeric strings, and txn_detail needs netAmount and currency as well as txnAmount.

`txn_detail.id` must be present and parse as an integer. The conversion calls `.unwrap()` on the parsed value, so a missing or non-numeric `id` panics the handler - the connection is closed with no response instead of returning a 4xx. This is the legacy Groovy-era feedback schema. The internal `txn_detail` / `txn_card_info` objects carry many fields; the shape above shows the top-level structure. Prefer `/update-gateway-score` for all new work.
