/**
 * Email Providers Detail API Route Handlers for Next.js
 *
 * These route handlers can be re-exported in your Next.js application to provide
 * individual email provider management endpoints at /api/email-providers/[id].
 *
 * Services are auto-initialized on first request using environment variables:
 * - DB_DIALECT: Database dialect ("postgresql" | "mysql" | "sqlite")
 * - DATABASE_URL: Database connection string
 *
 * @example
 * ```typescript
 * // In your Next.js app: app/api/email-providers/[id]/route.ts
 * export { GET, PATCH, DELETE } from 'nextly/api/email-providers-detail';
 * ```
 *
 * Auth is a header-only presence check; real verification lives downstream.
 *
 * @module api/email-providers-detail
