Fix double navigation on workout log row tap

A row tap pushed twice: a value-based navigationDestination(for: String.self)
collided with the row's NavigationLink(value:), surfacing a duplicate split list
over the hidden exercise detail. Rows now use a destination-based NavigationLink,
leaving navigationDestination(item:) as the view's only destination.
