[18.0][FIX] base_geoengine

Guard GeoEngine renderer and info-box popup against missing data.

Context:
In the GeoEngine (map) view of base_geoengine, several JavaScript errors occurred when interacting with the map, the records panel, and the infobox popup. These errors were reproduced in Field Service → Orders (map view), but the root cause lies within base_geoengine and affects any model using GeoEngine views.

Bugs fixed:

1. Exception when zooming to a record without geometry.
2. Exception when rendering the infobox popup. The info_box template accesses the fields as record..value, but renderingContext exposed the relational record (whose fields are in _values/data, not accessible as .value). Furthermore, if the template referenced a field not declared in the view, record. was undefined and .value threw "Cannot read properties of undefined (reading 'value')".
