i18n: add quick-picker strings and reduce-motion settings toggle

Five new keys across the EN source plus 24 locale variants (DE plus
23 AI-assisted, each carrying the pending-review marker): the header
quick-picker tooltip and two section headers, plus name and
description for a new ReduceMotion checkbox.

ReduceMotion was a config field with no UI -- the checkbox lands in
the Theme & Layout tab's window-style section. Designer.cs hand-edited
as a v1.5.4 block matching the v1.4.8 convention.
