[codex] fix route updates

[martin18f]

What changed

• Clear the selected parent location when a user edits or deletes a previously selected start, stop, or destination search value.
• Reset stale route state, rendered directions, travel time, and route-derived distance whenever route inputs change or endpoints become incomplete.
• Recalculate Google Directions after start/destination/stop/avoid-highways changes and ignore stale async route responses.
• Add tests covering route recalculation after adding/removing stops and clearing start/destination fields.

Why

The UI could keep an old DirectionsRenderer result and old distance/cost calculation after a route field was edited or cleared. The search input changed visually, but the selected location stored in app state remained valid, so the map and cost estimate stayed tied to the previous route.

Validation

• CI=true npm test -- --watchAll=false
• npm run build

Note: gh is not installed in the local environment, so this PR was opened with the GitHub connector after pushing the branch with git.
