feat(todo): a project as a table on wide windows (ADR 0033, D36)

Task, date, deadline, priority and labels in columns under a heading that
stays. A phone isn't offered it and shows a project kept as one as a list.

Whats-New: Table: on a wide window a project can show its tasks in columns, through Display.
Whats-New-De: Tabelle: In einem breiten Fenster zeigt ein Projekt seine Aufgaben in Spalten, über Anzeige.
