Note

Low Risk
Primarily deletes unused UI code and renames/moves the About tab component; behavior changes should be limited to settings navigation and About rendering.

Overview
Removes the legacy Settings search components (settings-search and settings-search-list) and drops the related i18n strings (missingSetting, missingSettingRequest) across locales.

Moves/renames the Settings > About content from the old InfoTab to a new settings-v2 AboutInfo component, updates the About tab to render it, and adjusts the unit test/baseline to match the rename and updated warning expectations.
