URL: https://github.com/apache/superset/pull/38405#issuecomment-4054576791
## **Sequence Diagram**
This PR adds chart_type_display_name to chart responses by mapping internal
viz_type values to readable names. During chart serialization, the MCP service
resolves names from frontend JSON overrides plus legacy Python metadata, then
returns both internal and display fields.
