CI / quality (push) Canceled after 0s
Replace the flat two-column layout with a guided 4-step wizard (Grundlagen -> Inhalte -> Abschnitte -> Medien) using the existing wizard progress model: - A top stepper shows each step's number/label and completion (check), and jumps to any step on click. - One step is visible at a time in a single comfortable centered column; the others stay mounted but hidden, so every named field still submits. - Footer navigation: Zurueck / Save as draft / Weiter, with Save Project on the final step. No field-name or save-logic changes. All 375 tests pass; tsc and eslint clean.
