Street Level: the action's failure cards in the interface language

The voice card showed English for show_street_level failures the catalog
did not know: a missing key, a map or source that could not be switched on,
the layer, invalid coordinates, an imagery fallback and the filter clause.
They now translate like the other action errors (exact messages and
patterns in speech.js), in all twelve languages; the spoken line stays
English, and the filter clause names the filters as their chips do.
