Mark user-configurable classes as final (part 8/21)

Add the C++ `final` specifier to leaf, user-configurable component classes and automation action/trigger/condition primitives so that classes meant to be terminal cannot be subclassed by external components. Only classes never used as a base anywhere in the tree are marked. Part 8 of 21, split alphabetically by component (hm3301 .. integration).
