fix(posts): post CI Fiber cut-offs in their sequence, not last

b0997f6 moved every cut-off after the parts. Plate.Parts order is the
cut sequence, and the user sets each cut-off's place in it (Set
Sequence), so the post must follow it rather than reorder. Cut-offs
still post as uncompensated open lines with no lead-in.
