Changelog

0.0.10

Models parsed from a PayWay response now keep that response verbatim on raw. Parsing is lossy — keys PayWay sends but the dataclass does not declare are dropped (a real transaction loses creditCard.cardScheme and creditCard.cardType), absent keys come back as explicit None, and aliases rename them (maskedCardNumber is stored as cardNumber) — so to_dict() is a projection, not the payload. Callers persisting responses for auditing, reconciliation or dispute resolution should store transaction.raw. Models you construct yourself leave it None, and raw is not a dataclass field, so to_dict(), equality and repr are unchanged.

Add search_transactions_by_customer(), search_transactions_by_receipt() and search_transactions_by_order(), matching PayWay's three documented search paths. Parameters are passed as query params and an optional page supports pagination.
Breaking: remove search_transactions(query). It built GET /transactions<query>, and /transactions only accepts POST, so any query that wasn't a /search-* path failed with 405 Method Not Allowed. Use the three methods above instead.
Add an optional page argument to list_customers(), so results past the first 20 customers can be reached.
Breaking: constants.TOKEN_URL now holds /single-use-tokens, the endpoint PayWay actually documents. The old value, /single-use-tokens-redirect, is not a PayWay endpoint and was unused. constants.TOKEN_NO_REDIRECT is removed — use TOKEN_URL.
Breaking: remove the unused constants.OWN_BANK_ACCOUNTS_URL.

Add opt-in transport retries to Client via max_retries and retry_delay constructor kwargs, following PayWay's retry guidance: resend on connection errors, timeouts and HTTP 429/503 (honouring Retry-After), never on other status codes, and never for a POST without an Idempotency-Key.
Behaviour is unchanged unless max_retries is set — the default (max_retries=0) keeps the existing single-attempt behaviour.
