Refactor API routes and hooks to use library clients

- Wire `api/geocode` and `api/bike-route` to use `GeocodingClient`
  and `BikeRoutingClient` instead of raw fetch calls
- Move `parseHafasJourneys` from `useJourneys` to `hafas-client`
- Remove dead code `src/lib/live-status-utils.ts`
- Update test setup to import `@testing-library/jest-dom/vitest`
