fix: update tab selection unconditionally for consistency

Apply Copilot suggestion to always update selectedTab binding value,
even when tapping the same tab. This ensures the TabView selection
stays in sync and simplifies the binding logic.

Setting the same value is harmless in SwiftUI and prevents potential
sync issues between the intermediate binding and the actual state.
