feat(workouts): save an edited resubmit of a hand-entered workout

The manual form sends one manual: id per opening and resends it after
an edit. The batch route now treats a MANUAL entry with a manual: id
as an overwrite, the way stats: measurements are: the stored row takes
the new values and the entry reports "updated", or "duplicate" when
nothing changed. Records keyed on the workout are removed under the
personal-records lock and re-derived. Every other id stays
first-write-wins. The status enum gains "updated".
