Complete German translation of unfinished terminal-label strings

qet_de.ts had 20 unfinished entries in the PartTerminal and
TerminalEditor contexts: 12 empty ones (shown in French at runtime,
since French is the source language of the tr() literals) and 8 that
already carried German text but were still flagged unfinished.

Translate the 12 empty strings, matching the terminology already
established in these contexts (borne/terminal -> "Anschluss",
label -> "Beschriftung", cadre -> "Rahmen", police -> "Schriftart"),
and mark the 8 existing drafts as finished. lrelease now reports
2621 finished and 0 unfinished translations for de_DE.
