nearby view: react to user location

[miles-grant-ibigroup]

Description:

The nearby view was ignoring the user location. This is not a good thing! This PR makes use of the user current position, regardless of how we get that position.

PR Checklist:

• Does the code follow accessibility standards (WCAG 2.1 AA Compliant)?
• Are all languages supported (Internationalization/Localization)?
• Are appropriate Typescript types implemented?

I think this is causing a bug where when you navigate to Nearby View from elsewhere, the useEffect triggers and immediately redirects to the current location if it's present. I think a better way to handle this would be to use the new function that I added that calculates which location to use for the nearby view. Then we can use the user's current location if we don't have one from the URL.

Works much better, thank you! The only other thing that would be a nice to have is zooming the map to the user's location when you navigate to the nearby view without a set location. (as is, the map doesn't move, so the nearby view center could be off screen)

I think this behavior is covered by another PR!

Looks good!
