refactor(server): centralize remote address selection

Unify remote address resolution so startup logging, primary remote URL selection, and /api/meta all consume the same server-side policy. Keep all external addresses user-visible, preserve stable interface ordering, and only de-prioritize link-local addresses when choosing the primary recommended remote URL.

On the UI side, introduce a shared helper that keeps the first remote address visible by default and collapses the remaining addresses behind a reveal action, with i18n coverage and targeted tests for the new selection behavior.
