Tasks now carry a tick box rather than being read-only rows. Ticking strikes
the title through and leaves the item in place, so a day still reads as a
record of what was asked rather than only what is left.
New in designs/Checkbox.dart:
- TickBox the square box itself, animating between empty and filled
- TickRow box + struck-through title + caller-supplied detail and trailing
- addTaskAffordance the centred "Add new task" control beneath a day's list
Applied to the home plan, the overdue queue and the goal task list. Each
screen holds a set of optimistically ticked ids so the tick lands immediately
and rolls back if the call fails; the set is reconciled whenever fresh data
arrives.
A tick completes the item outright, whatever its proof requirement. The proof
flow is still reachable from the Complete button in the overdue queue, so
tasks that need an artefact have a route that asks for one — but the tick
itself no longer enforces it.
Late completes stay visually distinct: the row keeps a Late pill and the
warning accent, and the user is told the window had already closed.
