QR code GeoJSON keys #3798

Current GeoJSON notation in QR code holds geometry and name of the site.

For completeness, should also hold:

• Date & time of geolocation
• Name of survey
• (Name of job?)

Not more, not to bloat the QR code.

NB: Relates to why instructions should be adjustable for the "Name this location" prompt #3744 (naming conventions make geolocations better identifiable).
