KNOW My Voice — Live Responses

How this admin page works: Every save on /my-civics-girl-know-your-voice/ writes a row to the Supabase table public.mgp_know_my_voice. This page reads rows via RLS policy mgp_kmv_select_admin, which requires profiles.role IN ('platform_admin', 'super_admin'). Anonymous girls appear tagged as such (no user_id, only an anon_id from their browser). If a girl checked "Share with the MGP community" it's tagged Shared — those responses can also be surfaced on a future public "Wall of Voices" via the share_publicly = true RLS policy.
