fix(email): show an unauthorized signing key as its own verdict

- map host validity 10 (key not authorized) to a new badge state
- rank it between "could not be checked" and "bad signature"
- word it on the badge, security view and report, not as BAD
- carry it through the verification payload by name
- translate the new strings in every shipped locale

         <source>**Note**: the signed part is not in canonical form, because its line endings are not CRLF. Something rewrote this message after it was signed, which is usually a program that changed line endings while saving or copying it. A signature cannot verify against these bytes, and importing the sender&apos;s key will not change that.</source>
         <translation>**Hinweis**: Der signierte Teil liegt nicht in kanonischer Form vor, da seine Zeilenenden nicht CRLF sind. Etwas hat diese Nachricht nach der Signierung umgeschrieben; das ist in der Regel ein Programm, das beim Speichern oder Kopieren die Zeilenenden geändert hat. Eine Signatur kann gegen diese Bytes nicht verifiziert werden, und das Importieren des Schlüssels des Absenders wird das nicht ändern.</translation>

         <source>The signed part contains line endings that are not CRLF, which is not the form the signature was computed over. Something rewrote this message after it was signed, usually a program that changed line endings while saving or copying it, not an attack. The signature cannot verify against these bytes, and importing the sender&apos;s key will not change that. Checking it needs the original, unmodified message.</source>

         <source>The signed part contains line endings that are not CRLF, which is not the form the signature was computed over. Something rewrote this message after it was signed, usually a program that changed line endings while saving or copying it, not an attack. The signature cannot verify against these bytes, and importing the sender&apos;s key will not change that. Checking it needs the original, unmodified message.</source>
         <translation>İmzalı parça, imzanın hesaplandığı biçim olmayan CRLF dışı satır sonları içeriyor. İleti imzalandıktan sonra bir şey onu yeniden yazmış; bu genellikle bir saldırı değil, kaydederken veya kopyalarken satır sonlarını değiştiren bir programdır. İmza bu baytlara göre doğrulanamaz ve gönderenin anahtarını içe aktarmak bunu değiştirmez. Kontrol etmek için özgün, değiştirilmemiş ileti gerekir.</translation>
