Cream page background end-to-end: Dockerfile PWA colors, README, verify block

Follow-up to the custom.css/custom2.js change: the Dockerfile seds the web
manifest theme_color/background_color and the index.html light meta to
#eaf3ea, and the README's verify block asserted the green wash as correct
("an earlier version of this block asserted cream ... would have led you to
fix a correct deploy"). Both are the same regression: the wash was rejected
earlier, restored by accident, and then documented as intended.

- Dockerfile: manifest + index meta -> #faf8f5 (cream), with an explicit
  "keep these three in sync" note (this sed, custom.css html:not(.dark),
  custom2.js COOP_BG.light).
- README verify block: asserts cream again, plus a new step for the
  install-time colors no DOM check covers (manifest + light meta).
- README palette section: hover is #f0ede6 not the wash; --presentation is
  cream; source of truth is the DEPLOYED CSS of dashboard/portal/panel, with
  the read command; records the shared 4.32:1 / 3.93:1 accessibility caveat;
  notes that cloudron exec silently swallows multi-line sh -c.
