Fix the cleanup prompt language and harden detection parsing

Review found the detected language was only switching the glossary rule, not
the base prompt: a detected Turkish recording with an English interface got the
English cleanup prompt with a Turkish glossary footnote. Both now follow the
spoken language, and the detected-language value is guarded against a server
that returns something other than a string. The record reply is covered by a
CLI test.
