Reorder the `## Prerequisites` bullets in 9 modules so prior modules
are listed lowest number first instead of by pedagogical importance or
at random. A trailing "Helpful but not required" group stays last and
is sorted within itself; multi-module bullets sort by their lowest
number. Intro/closing paragraphs are left in place. Prose is unchanged;
only bullet order moves.
Modules touched: 7, 9, 14, 15, 22, 24, 25, 26, 27. The other 18 modules
were already ascending (or have one/zero prereqs) and are untouched.
Module 19's "Helpful but not required: Module 16" correctly trails its
ascending 8/14/18 main list, so it stays as is.
