URL: https://github.com/apache/superset/pull/38277#issuecomment-4054213860
## **Sequence Diagram**
This PR fixes key MCP failures by adding DAO-level handling for dashboard
and dataset owner or favorite filters, then returning stable paginated list
results. It also changes URL chart preview behavior to return an explore link
for saved charts instead of failing as an unsupported format.
