Localize dashboard shell and home page.

Convert the dashboard layout (sidebar nav, header, role badges, wallet,
sign-out, language switcher) and the dashboard home page to the i18n
dictionaries, including a shared deployment-status label map. Switch their
links/router to the locale-aware helpers and add RTL-aware spacing.

Remaining dashboard page bodies and shared components still render English
copy and will be localized in follow-up commits.
