Adds functionality to search for places along the navigation route.
- Introduces `placesAlongRoute` and `routeReady` StateFlows in `MainActivity` and `NavigationViewModel` to manage search results and route status.
- Passes these states and `onClearSearchResults`, `onSearchClicked` lambdas to `NavigationScreen`.
- Implements UI in `NavigationScreen` to:
- Display search results in a card below the map.
- Allow clearing search results via a close button.
- Provide example search buttons ("Spicy Veg", "Pizza") when the route is ready.
- Implements `searchAlongRoute` function in `NavigationViewModel` to use the Places API searchAlongRoute functionality to fetch places.
- Implements `clearSearchResults` function in `NavigationViewModel` to clear the search results state.
- Adds a route changed listener in `NavigationViewModel` to set `routeReady` to true when a navigation route is established.
- Adds `SearchAlongRouteExample.kt` as an example class demonstrating how to use the `NavigatorListener` and perform place search along the route when a route is established. This class serves as a demonstration and potential helper for integrating the search functionality.
