feat(todo): the person's tasks, sections and labels, sealed and synced (ADR 0033, D6)

Browse source 
A table's rows are sealed for their table and row by one SealedRows,
which the repositories of projects, sections, tasks and labels share,
each table with its own sync gateway, a deletion blanking its rows first
in one transaction. A task's payload holds its title, description,
project, section, parent, place, date (a day, an optional wall-clock
time and duration), deadline, priority, labels and when it was done;
deleting a task deletes its sub-tasks, and a project or a section goes
with its tasks. Rows that don't open show locked; a device without the
account's keys writes nothing.
