to /onboarding. Route project variant to /app with the new space selected;
keep /onboarding for global New space when a first bot is still needed.

Wire the Projekte sidebar + and empty-state action to NewSpaceDialog
with project labels instead of the group creation panel. Keep space
wording for the global create menu. Add de locale strings and an e2e
regression test.
