I recently made a steam bear with a WYeast lager yeast (I don't remember the
number, but could look it up). I too fermented at 50-55 degrees. All
visible activity seemed to have stopped within about 10 days. I let it sit
two weeks, racked to a secondary, dry hopped, and let it sit another 5 weeks
at the same temp. My brew was just extract, hops, water and yeast. It came
out very "dry" (seems to have replaced "lite" in beer-marketing-speak). I
expect your fermentation was complete on schedule. See the other articles on
CO2 capacity of liquids vs. temperature.
