Show a Meta ad set’s targeting

Renders one ad set's targeting exactly as Meta holds it: locations, age, gender, detailed targeting, custom audiences, placements, devices and the Advantage+ audience setting. Use when: the user asks who an ad set reaches, or before meta_update_ad_set so the merge starts from a shared understanding. Do not use for performance — meta_get_adset_performance answers how it is doing. Returns both a readable table and the raw spec, so the ids needed for a later edit are already at hand. Free: this call does not cost a task.
