Which platforms this organization has connected and the health of each.

• The CHEAPEST discovery call in the API: a plain database read, no date range, no platform fan-out.
• Returns id (the integration UUID the /api/analytics/integration/{id} routes take), platform, status, account_id, account_name, connect_type, account_timezone, last_synced_at, last_error.
• Credentials are never returned: encrypted_credentials is excluded at the query level, so no request shape returns it.
