* Rename addon/addons to app/apps in filenames and imports
Continues the addon→app terminology migration (#6786).
Renames all source files, test files, fixture files, and
directories that contained 'addon'/'addons' in their names,
and updates all imports accordingly.
Resolution check files in supervisor/resolution/checks/ that were
renamed override the slug property to preserve the existing API
contract (slugs are exposed via the resolution info API and used
to run checks by name).
