Currently Query tabs in explorer do not support view options e.g. table
vs chart. This adds display state to query tabs to match the behaviour
of Notebooks
## To test
- create a query in explorer
- Run a query
- Set the display options via toolbar

## Summary by CodeRabbit
* **New Features**
* Query results can now be displayed as either a table or chart.
* Chart settings are saved with each query draft and restored when
reopened.
* Display preferences are maintained independently across query drafts.
* Editing a preview query now converts it into a permanent tab.
* **Bug Fixes**
* Invalid or legacy display settings safely fall back to the table view
without removing saved drafts.
* Charts and empty states now use the available editor space more
effectively.
