Fix dismiss from detail view dismissing wrong session

When entering detail view from mission's Attention panel, the tasklist
cursor doesn't change. So DismissSelected() was dismissing whatever
the tasklist cursor pointed at, not the session displayed in the detail
view.

Now the detail view dismiss reads the session from taskDetail.Session()
and dismisses it by ID, ensuring the correct session is removed
regardless of how the detail view was entered.
