[PM-20041] Deleting Notifications when Task is completed (#5896)

* mark all notifications associated with a security task as deleted when the task is completed

* fix spelling

* formatting

* refactor "Active" to "NonDeleted"

* refactor "Active" to "NonDeleted" for stored procedure

* only send notifications per user for each notification

* move notification status updates into the DB layer to save on multiple queries and insertions from the C#

* Only return UserIds from db layer

* omit userId from `MarkTaskAsCompletedCommand` query.

The userId from the notification will be used

* update UserIds

* consistency in comments regarding `taskId` and `UserId`
