-- =====================================================================
-- CONTENT SCHEMA — Part 17: AI settings (per-tenant OpenAI config)
-- Stores the OpenAI (or OpenAI-compatible) API credentials used by the
-- AI SEO content generator. One row per tenant; api_key is stored as-is
-- (self-hosted) and never returned in full to clients (masked in the API).
-- base_url is configurable so deployments behind a proxy / in restricted
-- networks can point at a reachable OpenAI-compatible endpoint.
