feat: improve directions panel with route legend and place card below

- Add route legend showing wilderness (dashed orange) vs road (solid blue)
- Show place card below directions panel when clicking map during routing
- Clean up error messages to be user-friendly (no offroute text)
- Legend only appears when route has wilderness segments
