Subject: [PATCH] Fix participant matching failing due to updating all columns
 instead of only changed fields (#18105)

The updateMany in matchParticipants was spreading the entire participant
object into the SET clause, which included generated columns
(searchVector) and composite field columns (createdBySource) that can't
be written to. Narrowed the update to only set personId and
workspaceMemberId.
```
