[bug] Discover UI stuck on searching after deleting index pattern (#8659)

* [bug] Discover UI stuck on searching after deleting index pattern

When using Discover with query enhancement enabled, deleting an index pattern from Index Management does not properly update the "Recently selected data" list in Discover. This causes the UI to become stuck in a "Searching" state when attempting to use
Discover after deleting an index pattern.

Handle the error case where the use index patterns hook caught error when
enhancements was enabled.

Improve Empty State Handling: Add No Index Patterns Panel with Data Selection in Discover View (#8613)

* Improve Empty State Handling: Add No Index Patterns Panel with Data Selection in Discover View

This PR primarily addresses the scenario when no index patterns (general) is available in the Discover view.
Instead of redirecting users to the index management page, it introduces a new "No Index Patterns" panel.
This panel provides users with the option to open a data selector and add index patterns
directly from the Discover view, improving the user experience for new or empty deployments.

To achieve, we move the selectedDataset state from ConnectedDatasetSelector to the app container's
state management. This allows the AdvancedSelector, opened from the AppContainer, to update
the dataset state effectively. Key changes include:

* Implementing NoIndexPatternsPanel and AdvancedSelector components.
* Refactoring dataset state management in AppContainer and Sidebar.
* Modifying DiscoverCanvas to conditionally render NoIndexPatternsPanel.
* Updating ConnectedDatasetSelector to use shared state and dataset change handling.

* Update design of no data selected
* use i18n
* fix comments
* Update design of no data selected
* fix lint error
