/**
 * Email Providers API Route Handlers for Next.js
 *
 * These route handlers can be re-exported in your Next.js application to provide
 * email provider management endpoints at /api/email-providers.
 *
 * 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/route.ts
 * export { GET, POST } from 'nextly/api/email-providers';
 * ```
 *
 * The list endpoint is not server-paginated; admin code reads the array
 * length directly. There is no synthetic `meta.total`.
 *
 * @module api/email-providers
