- reject blank viewport-bias components before Number() reads them as 0
- give the upstream call a 10s deadline and a 256 KiB capped body read
- return fixed public text on failure instead of the upstream message
- Google's Geocoding web service refuses referrer-restricted keys, so the
browser call forced GOOGLE_MAPS_API_KEY to ship unrestricted
- add /api/google/geocode and /api/google/reverse-geocode, using the server
key like Places and Street View already do
- the browser key now needs the Map Tiles API only
