Description
### Bug Type (问题类型)
None
### Before submit
- [X] I had searched in the [issues](https://github.com/apache/hugegraph-toolchain/issues) and found no similar issues.
### Environment (环境信息)
- Server Version: v1.0.0
- Toolchain Version: v1.0.0
- Data Size: xx vertices, xx edges
### Expected & Actual behavior (期望与实际表现)
schema:
SchemaManager schema = hugeClient.schema();
schema.propertyKey("testBlob").asBlob().ifNotExist().create();
code example:
GraphManager graph = hugeClient.graph();
Vertex user1 = graph.addVertex(T.LABEL,"USER", T.ID,"user_1",
"testBlob", Blob.wrap(s.getBytes()));
error message:
java.lang.IllegalArgumentException: Invalid property value type: 'class org.apache.hugegraph.util.Blob'

at org.apache.hugegraph.driver.GraphManager.attachProperties(GraphManager.java:469)
at org.apache.hugegraph.driver.GraphManager.addVertex(GraphManager.java:71);
cause of error:

there is no Blob type in the verified class
### Vertex/Edge example (问题点 / 边数据举例)
_No response_
### Schema [VertexLabel, EdgeLabel, IndexLabel] (元数据结构)
_No response_

Research direction
Start with the reported path in GraphManager.attachProperties and GraphElement.property, then reproduce the addVertex example using a Blob property created through schema.propertyKey(...).asBlob(). The work is done when the example no longer raises Invalid property value type and the Blob attribute is written successfully.
