feat(about): give the site a named author

The site had no author, no statement of why it exists and nobody
accountable for its numbers, which is most of why it reads as machine
generated.

The page states plainly that its author is not an education expert. The
credibility claim is lived experience — a parent going through primary
admissions — plus stated provenance for every figure, which is true and
cannot be undermined by someone noticing there is no teaching
qualification behind it. First name only: the Person JSON-LD carries no
familyName, worksFor or affiliation, and a test asserts it stays that
way.

The footer gains a fourth column, with a tablet breakpoint so four
columns pair up rather than crushing before the 768px collapse. The nav
is deliberately untouched — its mobile tab bar already carries four
items.

public/brand/tudor.jpg is NOT in this commit. The page references it and
will show a broken image until the photograph is supplied; a stock
portrait would defeat the entire point of the work.
