Change to 'Marked Items as Discussed' in Check-In documents functionality

Following 25C upgrade, noticed that 'Marked Items as Discussed' button has changed behaviour. The previous behaviour was that both the employee AND the line manager had to 'mark items as discussed' (they had their OWN toggle button) and had an area to add their own notes.

Now it appears to be a shared toggle button so technically, the employee could mark as discussed but then the leader could override and unmark it and vice versa).

Previous workflow was both party had to accept it as discussed. Once the check-in meeting was held, employee goes back into the check-in document, adds notes and marks as discussed (employee marks as discussed). Only ONCE the employee has done this, can manager go back in, add their respective notes and mark as discussed and the check-in will then show 'Completed'.
