Ning Sun 0f118bc5ba fix: serialize struct to json in postgres (#9170) ...

* feat: serialize struct to json in postgres

* fix: support view scalars and preserve null structs in scalar-to-value conversion

Address PR review:
- Utf8View/BinaryView ScalarValues now convert like their non-view forms
  instead of failing row extraction for struct columns
- a null struct scalar converts to Value::Null so a null struct inside a
  list stays null in the serialized JSON

* fix: return errors instead of panics for unsupported arrow field types

Struct-typed query results with arrow field types greptimedb cannot
represent (e.g. Decimal256) used to panic during schema conversion and
row extraction, dropping the client connection. They now surface as
query errors:

- ConcreteDataType::try_from builds struct types fallibly via the new
  StructType::try_from_arrow_fields
- Value::try_from(ScalarValue::Struct) uses the same fallible path
- new try_value_from_array converts an arrow element to Value with
  error propagation, used by the postgres struct encoding
