Renaming a chart does not update the overview list

[tenthe]

Body

When a user updates a chart name and returns to the overview using the back button (top left), the chart list still displays the old name.

The issue originates in ChartViewComponent within confirmLeaveDialog, where navigation occurs before the save request has finished.

@siddharthbaleja7 I've assgined you the issue.

@dominikriemer I wanted to discuss my approach before opening a PR:

Current Problem:
In confirmLeaveDialog, the save request is triggered asynchronously, but the function immediately returns true. This allows the router to navigate away before the save completes, causing the overview to load with potentially stale or incomplete data.

Proposed Solution:

• Use switchMap to chain the save request with the navigation action.
• Ensure the router waits for the save to complete successfully before navigating back to the overview.
• Handle errors gracefully so that if the save fails, navigation is prevented and an error message is displayed.

I’d like to confirm this approach aligns with expectations before I start the PR. Feedback is welcome!
