fix(a11y): suppress disabled-control contrast findings on the rule

WCAG 1.4.3 exempts inactive components from contrast requirements, so
Inspect's Run button — disabled until a domain is typed — was reporting a
contrast failure that was never a real defect.

The first attempt typed a domain to enable the button. That worked for
the single-screen test but raised the keyboard, which then followed the
audit onto every later screen in the Dynamic Type sweep and reported nine
phantom hit-region findings per screen against the system emoji picker's
category buttons. Suppressing on the rule instead — drop contrast
findings whose element reports isEnabled == false — fixes it everywhere
with no UI manipulation.

Also documents that simulator keyboard state persists across runs, so a
dirty simulator inflates the burndown with system-UI findings. Erase and
re-run before believing anything that names system UI.
