Map style and feature visualization feedback

[rasagy]

Per voice w/ @ajithranka, opening this ticket to see if we want to rethink or update any part of the map style or the way we visualize the features (points/lines/polygons). We currently use Mapbox Streets and use an opaque dark red color for features.

Quick screenshots of how it looks right now:

I'm working on these features to add here:

• Show a bounding box around the features and set the map to cover the bbox.
• Show geojson properties of a feature on click.
