fix(idempotency): fix serialization of Pydantic idempotency keys for special data types

[jontmy]

Issue number: closes #8065

Summary

Changes

• Updated the Pydantic serialization mode of idempotency keys to use mode="json" instead of relying on the default mode="python"

User experience

Before: Special data types such as UUID and dates cannot be used in idempotency keys because they cannot be serialized by Pydantic's default .model_dump().

After: Setting mode="json" allows Pydantic to convert supported data types (such as UUIDs) to valid JSON values, allowing them to be used as part of idempotency keys. If an unsupported type is used and can't be serialized to JSON, a PydanticSerializationError exception is raised.
