instead of "Hiking". Profile order: fastbike, safety, shortest, car,
trekking.

Initialize i18n via initI18n() in both root.tsx files and replace all
hardcoded user-facing strings with useTranslation() calls. Adds missing
translation keys for planner (profiles, connection states, save flow)
and journal (auth pages, route management, passkey prompts).
Both English and German translations are complete.
