fix(review): mannequin down 2 cm; 8 and 9 approved

Owner review: rows 1, 2 and 3 show the mannequin about 2 cm too high; rows 8 and 9 show nothing wrong.

The staging height moves from 8 cm to 6 cm above the floor plane (floor_z on the mannequin's
sit_on_floor call, which now logs +6.0), and rows 8 and 9 are approved. Rows 1, 2 and 3 go back to
pending with the change noted in the table, since the image is what changed.

Captures regenerated.
