We do not, by design, add Time module for hub's children.
This has a side-effect that we need to fallback to the parent's time
module to allow presenting the correct timestamp for the last alert.
Address the inconsistent naming of smart modules by removing all "Module" suffixes and aligning filenames with class names. Removes the casting of modules to the correct module type now that is is redundant. Update the adding of iot modules to use the ModuleName class rather than a free string.
