Converts the raw prepare() fixtures and reads in the document sync service
spec to the ORM factories and readers. The row builders (bindings, sync
items, files, the connection) and the files service double write through
insertRow and updateRows and are async now, the shape the real service has;
the row readers go through findRow and findRows. Seeding that ran inside
Array.from callbacks is a plain loop, so every row is written before the
run it feeds starts.
Three reads stay raw behind allow markers: the helper that takes a time
from SQLite's own clock and the two checks that compare a stored timestamp
with CURRENT_TIMESTAMP and julianday('now'), since the clock is what they
are about.
