Substitutes the real admin UID everywhere the placeholder appeared,
points the Edge Functions base URL at the deployed project, and adds
production JWT verification: trigger functions now send the anon key
as a bearer token so verify_jwt can stay enabled instead of leaving
the functions open to unauthenticated calls from the public internet.
Also adds scripts/create-admin.ts (one-off helper used to create
Mira's admin auth user), documents the seed script's non-VITE env
vars in .env.example, and closes a gitignore gap where plain .env
wasn't excluded alongside .env.local.
