Add the setup flow's browser journeys, axe sweep and string-headroom check

Four journeys, one account each, from the welcome screen to the
dashboard: blood pressure and weight typed in, a daily medication added
inline, a visit within a month with labs, and a child's managed profile
created on the confirm screen. Each asserts what the walk wrote — the
module map, the tile order, the checklist, the settled ledger — and the
first proves that leaving after Q3 resumes at Q4.

Two sweeps on accounts of their own drive the state through the answers
route and visit every screen by URL: axe at both widths plus one
keyboard-only answer, and every locale with every text node lengthened
by 30% before the page, the shell, every clipping box and every control
are measured. All six run in one project because each mutates the
account it walks.

The medication wizard learns to stay where it was mounted after a
create, which the first-result screen needs and the medications list
does not.
