📝 Walkthrough

Walkthrough

Updates ClientCollateralDetailScreen navigation to accept an onNavigateBack callback parameter, which is passed through the navigation route and integrated with MifosScaffold's back button handler, enabling proper navigation flow control.

Changes

Cohort / File(s)	Summary
Navigation Route Updates feature/client/src/commonMain/kotlin/com/mifos/feature/client/clientCollateralDetails/ClientCollateralDetailRoute.kt	Added named parameter navController and new onNavigateBack callback that invokes navController.navigateUp() when back navigation is triggered
Screen Composable Updates feature/client/src/commonMain/kotlin/com/mifos/feature/client/clientCollateralDetails/ClientCollateralDetailScreen.kt	Added onNavigateBack parameter to both ClientCollateralDetailScreen and ClientCollateralDetailScreenContent composables; wired callback to MifosScaffold's onBackPressed handler

Poem

🐰 A rabbit hops back through the collateral maze,
With callbacks now guiding through navigation's phase,
Each detail screen knows when to retreat with grace,
Back buttons aligned in their proper place! 🔙✨
