fix(settings): keep note and paste fields at 16 px on a phone

On /settings/anamnesis the four note fields were raw textareas styled
by three copies of a class constant with text-sm (14 px), and on
/settings/export the three paste fields used text-xs (12 px) and the
backup passphrase text-sm. iOS zooms the page into such a field on
focus and leaves it zoomed. The notes use the Textarea primitive now
and the export fields keep the small size only under a fine pointer.

The 16 px guard read the five field primitives and could not see a
call site override their size, or a raw field styled from a constant.
It now parses every field call site; four that are still small sit on
a list that only shrinks. The focus guard drops the three records
files, whose fields come from the primitive now.
