"""Regression tests: member-sheet writes must target columns by live header name.

The roster sheet gained a "Käepael" column after "Nimi". Writes used to take
their position from EXPECTED_HEADERS, so every write landed one column left -
the TRUE/FALSE synced flag overwrote "Roll", and /check then reported
"Rolli 'FALSE' ei leitud serverist" for every member.
