Description

Added bus route highlighting to the map! Now when you click on a bus (or choose "See all stops for this bus" from the stop sheet), it highlights the bus polyline and stops while turning the rest gray.

Changed Files

(Please list all files you changed, each with a description of what you changed and why.)
Tip: see a list of everything you changed on the "Files changed" tab

Example:

• map_screen.dart
  • Made the BusSheet modal half height and added calls to baseRoutesLayer.setFocusedRoute(...) whenever the bus sheet is shown
• onboarding_screen.dart
  • Disabled the scrim to avoid the background darkening as the user scrolls the BusSheet.
• base_routes_layer.dart
  • Added a focusedRoute variable to track which route is focused, and it now influences how polylines and stops are drawn (non-focused-route polylines are gray, and non-focused-route stops are hidden)
