docs/web-ui.md: scrub #NNN cookies from SCH3DUL3S section (mara on #744)

Same theme as the tabs.js scrubs in this batch — drop the 7 #NNN
cookies (#444, #459, #460, #467, #474, #535, #564) the SCH3DUL3S
section was carrying. The substantive prose stands on its own;
the citations were just attribution tracking that belongs in the
git log + issue threads, not the user docs.

Mara on #744: 'no docs md changes needed?' — yes, this.
