build: keep the DVD and MQTT helpers, and count the deletion honestly

Building the package showed what reading the tree did not: classroom-dvd
still calls classroom-window, classroom-mqtt still calls classroom-notify,
and the DVD overlay still imports the icon and stylesheet helpers the dock
shared. They go back in, and the write-up now counts what was actually
removed rather than what could be.
