New UX for Get Directions:
- DirectionsPanel component with two stacked input fields
- LocationInput component with autocomplete, coordinate parsing
- Swap button to flip origin/destination
- Travel mode selector (Drive default, Foot, MTB, ATV, 4x4)
- Boundary selector (only visible for non-Drive modes)
- Map click fills active input field with crosshair cursor
- Auto-route when both endpoints are filled
- X button closes directions and returns to search view
Store changes:
- directionsMode state for panel switching
- activeDirectionsField for map click targeting
- startDirections now enters directions mode with destination pre-filled
