Notifications currently only watch a single reserved list, `const.NOTIFY_LIST_NAME` (see `src/hatty/controllers/notifications.py`) — entities are watched by being members of that one special list. Instead, allow any user-created list (or multiple lists) to be designated/toggled as a notification source, rather than requiring membership in one hardcoded reserved list.
