/**
 * X (Twitter) App Config Model
 *
 * Platform-wide X (Twitter) OAuth 2.0 app credentials for the X integration,
 * managed from Super Admin → Settings (no .env editing needed). Stored as a
 * singleton document with companyId = 'platform'. Client ID and Client Secret
 * are AES-256-GCM encrypted at rest and excluded from queries by default.
 * Environment variables remain a fallback.
 *
 * `scope` lets a super admin control the requested OAuth scopes. X v2 is not
 * date-versioned (unlike LinkedIn), so there is no apiVersion field.
 *
 * Mirrors LinkedInAppConfig / YouTubeAppConfig / FacebookAppConfig.
