Add a :large FileAttachment style for full-width inline body imagesHEADmaster

Sized generously (1600x1600>) rather than against today's cramped
490px content column specifically -- shrinking an oversized source
to fit a narrow container is free and looks fine; a source too
small for a future, wider redesign has no fix short of re-uploading
every image. Purely additive: nothing reads :large yet, and
generate_variants already loops over the whole STYLES hash
generically, so no other code needed to change for new uploads to
start getting it. Test suite's own hardcoded style lists updated in
the same commit so they don't quietly drift out of sync with what
the app actually defines.
