Both changes fully implemented. Sync delta specs to main:
- map-display: add Planner home page nav and cursor rendering requirements
- planner-session: add session participant awareness requirement

Journal gets a nav bar in root.tsx with conditional links: Routes and
Activities for authenticated users, Sign In and Register for guests.
Active route is highlighted via useLocation(). User menu shows username
linking to profile and a logout button.
Planner SessionView header title becomes a home link back to /.
Adds i18n keys (en + de) for all nav labels. Updates E2E tests to use
scoped nav selectors now that links appear in both nav bar and page body.
