"""Tests for the DA_DF_TP2_20_COMMON AirDresser (model DF9500A, issue #157).

A different board generation than issue #162's DA_DF_A51_20_COMMON, routed
into the same air_dresser registry (both carry the '_DF_' modelNum token).
Exercises the two things this board does differently: a populated
/wm/editcourse/vs/0 (so cycle_options() never needs the supportedOptions
fallback #162 relies on) and the new /airdresseroption/sanitize/vs/0
capability #162's dump doesn't report at all.
