Let a German verdict reach the classifier the merge gave it

The two halves of the ECG fix were built apart. One taught the parser
Apple's full English verdict set; the other taught it the metadata keys and
verdict wording a German watch writes. Each was correct alone, and each
left "Sinusrhythmus" unresolved for a different reason.

Together they meet: the alias table translates the wording onto Apple's
own English, and the classifier decides what it means. One place still
owns the meaning, which is what stops a per-language verdict table from
drifting the first time Apple adds a case.

The test that expected null was pinning the gap between the branches
rather than a decision about German. It now expects NOT_DETECTED, and a
French verdict takes over the null case, because four of the six
languages genuinely have no observed key map yet.
