fix: Sub menu lists all profile subcategories so Disable/Enable all is reachable

Previously the Sub menu only showed folders from the current video's markers
plus configured subprofiles, so subcategories without clips on the loaded
video (or without a matching subprofile) never appeared. Now it also includes
every subcategory that has clips anywhere in the profile (active or disabled).
