Update origin/destination by pressing Enter

[luca-aurelia]

Users expect hitting Enter to update the map when they're editing the origin or destination. It doesn't.

Also, requiring an action to update the map is inconsistent with the rest of the UI, which automatically updates when the user enters a new value. Should we standardize on requiring actions to update? Or on instant updates?

Pros and cons

Instant updates

✅ faster results
✅ app feels responsive
🚫 don't get the satisfaction of pressing Enter and having everything update
🚫 wasteful intermediate calls to the Google Maps API
🚫 users might not notice that information has updated

Actioned updates

✅ satisfaction of hitting Enter and everything updates at once
✅ fewer calls to the Google Maps API
🚫 slower results
🚫 the Enter press isn't strictly necessary
🚫 where do we put the Update button?
