Carry the figure-style and table-order fixes into the release

The lower of two coinciding curves is the wide one, the random-guess
reference is dotted everywhere and never borrows a scheme colour, the
three collection SNRs in the known-plaintext figure differ by face and
width rather than by dash alone, and the legend floor now prints at six
points with an assertion that fails if any figure drags it lower. Both
table generators list the proposal first.
