feat(cli): add terminal-UI i18n runtime and upgrade Ink to 7 (U6)

Add a synchronous Node-side i18next instance built from the generated
@fusion/i18n CLI catalog map (no async backend, first frame localized), with
locale precedence --lang flag -> GlobalSettings.language -> env (LC_ALL/LANG/..)
-> en. Wrap the Ink DashboardApp render in <I18nextProvider> and thread a
--lang flag through runDashboard.

Upgrade ink 6.8 -> 7.0 (native CJK double-width measurement) and raise the
react/@types/react peer floor to ^19.2.0. A spike test confirms react-i18next
works under Ink's custom reconciler: localized first frame + re-render on
changeLanguage (including CJK), retiring the KTD1 unknown.
