test(e2e): journeys for row tags and pupil counts, and ask for page_size

Three journeys pin the fixes: a non-selective secondary's row has no
Selective tag, a school recorded with no religious character has no faith
tag, and the list and the school page agree on a secondary's pupil count.
Run against staging before the fix, all three fail.

The list API reads page_size. Nine journeys asked for per_page, which it
ignores, so each got the default 25 rows whatever it asked for.
