P11.6 diffuser wiki: banner hash + section 9 form completeness + section 14 category/colour notes

Browse Source 
- Bump banner hash from 15cfb22 → 8cc02ee (latest HEAD).
- Section 9: add missing `number` form field; mark localAtmPressure /
  waterDensity as hidden defaults with no form row; update mermaid diagram.
- Section 14: add issue #5 (category 'wbd typical' vs 'EVOLV') and issue
  #6 (S88 colour already set — §16 note now stale).
- npm run wiki:all run prior to edit; AUTOGEN markers untouched.
