feat(tasks): move, repeat, delegate and re-read a task from its drawer

Four things you could not do to a task you had open, and one that had
never worked at all.

**Project, recurrence and assignee** are now fields in the drawer. A task
created in the wrong place could only be fixed by dragging it, a repeat
could only be set by typing it into the title when the task was created,
and delegation had no interface whatsoever despite assignee_id being in
the API from the start. The assignee only appears on a project with
somebody else in it, because on your own there is nobody to choose.

**The title is read the way quick add reads it.** Typing "i morgen kl 14
p1" into a title used to leave it as those words, so where you typed a
sentence decided what it meant. The parse runs on the server — the
grammar is Danish and English and lives there — and applies only when it
consumed something. What it took is said out loud, and the fields on
screen are updated to match: the drawer otherwise seeds its inputs once
per task so a save cannot overwrite what you are typing, and that rule
has to bend exactly here, where the save changed the very fields in front
of you.

**And the member list has never worked.** The share panel, and now the
assignee field, ask for it. Every call errored: the ORDER BY named an
expression, and SQLite only accepts result-set columns across a UNION, so
it failed at query time with "1st ORDER BY term does not match any column
in the result set". Found by the smoke test that opens a task, which is
the second real bug that suite has caught by watching for failed requests
rather than only for what renders.
