This addresses a javascript error when printing directions. When a layer is not visible at the current zoom level, its value in an array of visible layers is undefined, causing an error when we retrieve layers in the print function. This change tests for the visible layer and, if missing, returns a simpler layer configuration.

After further discussion with Brendan of the GDX team, we agreed to reuse the same app ID in the tracker across hosted SMK apps. They distinguish sites by the URL of the apps the tracker sends requests from, so the app ID does not need to be unique per hosted SMK app.

This replaces ESRI legacy basemap API with new ESRI vector basemap API. Legacy basemaps are replaced with new ArcGIS basemaps except for Streets, which is replaced by the OpenStreetMaps Standard map instead of the ArcGIS Streets map.

The "esri-leaflet-vector" library is added. Basemaps are now added to a separate map pane having a lower z-index than map layers in order to prevent basemaps from covering layers. An ESRI API key, stored as a Github secret, is added to site configuration and used in basemap requests.
