feat(send): clear payload and idempotency key after sending by @Bjornftw in #12
Fixed an issue where the internal payload was not fully cleared between sequential send calls when reusing the same client instance.
In some cases, when sending multiple emails with attachments, attachments from a previous email could unintentionally be included in a subsequent email by the same sender.
- Affected: users of the PHP SDK who send multiple emails using the same client instance and use attachments. This does not introduce cross-account issues.
- Recommendation: upgrade to v1.4.1 if you send attachments via this SDK
