feat(theme-studio): move reuse context from app labels into a hover

Clean the app labels and move the "what reuses this" context into the app dropdown's tooltip, so the labels stay short. The foundational face sets name their consumers on hover: ansi-color (vterm, eshell, compilation, ghostel, eat), shr (eww, nov, mu4e/message), gnus (mu4e article view), and dired (dirvish). Labels now carry only the name plus any acronym expansion. A small APP_HOVERS dict in face_data.py feeds an app "hover" field that sets the dropdown's title on selection.
