refactor: provide navigation event dispatcher in Koin previews

- Wrap the `content` of the `PreviewKoin` composable with a `CompositionLocalProvider`.
- Initialize and provide a `LocalNavigationEventDispatcherOwner` using `rememberNavigationEventDispatcherOwner` to support UI components that depend on navigation event dispatching within Compose Previews.
