feat: add list view with GottesdienstCard components

- New GottesdienstCard component shows each service with its info
- Shows the currently logged-in user's mark as a toggle checkbox
- Lists ministrants who have responded with their mark status
- Admin view hides the checkbox, shows responses only
- New ListView wrapper renders all cards
- PlanView gets a Tabelle/Liste toggle between table and card views
