feat(tasks): add quick-status button to kanban cards (#24)

Adds a small button on each kanban card that cycles the task status
(open → in_progress → done → open) without requiring drag-and-drop.
Useful for touch devices and kiosk browsers (e.g. Fully Kiosk Browser)
where drag-and-drop is unavailable. All four locales updated.
