Refactor MapViewModel and MapScreen to remove NavigateUp event handling

- Removed NavigateUp event and action from MapViewModel and MapAction.
- Updated MapScreen to handle navigation directly without using the NavigateUp event.
- Introduced LaunchedEffect in MapScreen to update camera position based on location changes.
- Cleaned up unused imports and improved code readability.
