A medication can now hold multiple parallel schedules, each with its
own cadence and times. Steps 5-7 of the wizard become per-schedule;
Step 8 lists every configured schedule with edit and remove actions
and surfaces a "Weiteren Zeitplan hinzufügen" card at the bottom.
The hydrator reads every schedule on edit and lands the user
directly on the list view when more than one is present.
