RR40M7165WW is the fridge half of the same household dongle setup as
issue #77's freezer -- identical pipe-delimited ARTIK051_DONGLE_REF
modelNum, so the previous commit's detection and door-sensor fixes
already cover it with no further code changes. Add its fixture as a
second, independent regression case: it exercises the 'cooler' instance
segment instead of 'freezer' for both the temperature pattern caps and
DOOR_GENERIC, and notably reports /door/onedoorfreezer/vs/0 despite
being a single-door fridge (shared firmware naming across the product
line, not an actual second compartment) -- worth having its own golden
so that stays working too.
