 * Walks the create flow through to Step 8, then taps
 * "Weiteren Zeitplan hinzufügen" to append a second weekly Wednesday
 * schedule on the same medication. The list view surfaces both
 * summary cards before save, and the POST body carries both
 * schedules so the route can persist them in parallel.
 *
 * Use case the maintainer cares about: short-acting + long-acting
 * insulin on a single medication. Today the wizard collapses to one
 * schedule on save; compose-mode closes that data-loss gap.
