Bail on geolocation for manual input if it fails

[nickoneill]

Sometimes folks calling from overseas would say they could not set an address manually. This makes sense as we were constantly trying to navigate from the NoLocation state to the GettingAutomatically state even if it had previously failed. Instead, set the state to EnterManually if the server response from the reps endpoint returns an error.

Pull Request Overview

This PR improves the user experience when geolocation retrieval fails by updating the component's state to allow manual address entry. Key changes include:

• Introducing a new state flag (hasGeolocationFailed) to track geolocation failures.
• Short-circuiting the automatic location retrieval function when a failure is detected.
• Adjusting error handling in the geolocation promise chains by updating the component state accordingly.

Thanks for tagging me -- code looks good, though I dumbly can't figure out how to test this flow -- do you have to be in a non-us location and trigger "get location automatically"?

If we can request browser location, we try to do that first when a user taps "Set your location" regardless of location. If you have turned off location permission for the site you'll just see the manual flow so check if you have that denied somewhere.

This specific issue was triggering when a reps call was returning an error, very common if your browser location is outside the US. But we should always let people get back to manual location input if they want.
