Start a browser OAuth connect session
POST/auth/social-connect/start
Requires an API key (session fallback rejected with
401 api_key_required). For the browser-OAuth platforms (instagram,
facebook, threads, x, linkedin, tiktok, youtube, pinterest) this
returns the dashboard's OAuth-start authorize_url to open in a
logged-in browser, plus a session_id to poll. Headless platforms
(bluesky, telegram, discord) are rejected with
400 use_headless_endpoint — POST credentials to their dedicated
endpoints instead. mode: reconnect requires account_id.
