fix(manacore): show all open tasks in dashboard widget, not just today

The tasks widget only showed tasks with dueDate=today, so tasks without
a date appeared as "no tasks". Now fetches all open tasks via GET /tasks,
sorted by due date (today/overdue first, then future, then no date).

- Add getAllOpenTasks() to todo service
- Update widget to use getAllOpenTasks()
- Show due date label next to task title (with overdue highlighting)
- Update i18n: "Aufgaben heute" → "Aufgaben"
