fix(medications): keep a record-only schedule unless the write names trackIntake

The shipped iPhone app cannot see the schedule of a medication kept as a
record, because it is served with an empty schedules list. Its editor opens
such a medication as daily at 08:00 and, once any schedule field is touched,
sends a full replacement built from that default, plus asNeeded and oneShot,
and never trackIntake. On a record-only medication the update route now
drops schedules, asNeeded and oneShot from a write that does not name
trackIntake and applies the rest. The web schedule editor and the wizard
name the flag on every save.
