Unnecessary recomposition when navigating to the current screen from the TopBar #210

Issue Description

When a user focuses or clicks on a TopBar tab that corresponds to the screen they are already on, the app still triggers a navigation action.
This causes an unnecessary recomposition of the current screen, even though the user is not navigating to a new destination.

Expected Behavior

Navigation should only occur when the destination screen is different from the current one.
If the user re-selects the same tab, the app should remain on the current screen without triggering a recomposition.

Impact

• Unnecessary recompositions
• Performance overhead
• Potential negative impact on user experience
