fix: convert Jest mocks to Vitest in useSteamJourney tests

Replace jest.mock() and jest.* calls with vi.mock() and vi.*
for Vitest compatibility.

This project uses Vitest, not Jest. The Jest namespace was
causing TS2694 "namespace cannot be used as a value" errors.

Fixes ~20 TypeScript errors in passenger test files.
