localization: ship de-DE

Complete German catalog across all three namespaces, 1129 keys,
machine-translated then reviewed for terminology and plurals.

Fixed on review: "composer" (the chat input box) had been translated
as "Editor" in two shortcuts strings, colliding with this app's actual
Editor/Code-Editor feature — changed to "Eingabefeld". scopeDockers
had drifted from the lowercase, untranslated "dockers" every other
locale (including this one's own pt-PT/fr-FR precedent) uses for that
filter-scope label. All 17 plural entries verified at count 0/1/2 —
German uses the same one/other split as English, so this was mostly
confirming "0 Elemente" reads right, not hunting for a CLDR surprise
the way French needed.

SHIPPED_LOCALES and the three parity tests now include de-DE. es-ES
is drafted and under review — held out of the picker until it passes
its own pass.
