<!-- =============================================================================
// IT智能服务台 — 坐席登录页 (v1.1, 2026-07-04)
// =============================================================================
// 说明: 从扫码登录改为账号密码+OTP表单登录
//
// 流程:
//   1. 用户输入账号 + 密码
//   2. 点击登录 → 调用后端 /api/agents/login
//   3. 若 require_otp=true，显示 OTP 输入框
//   4. 用户输入 OTP 后再次提交
//   5. 登录成功 → 存 token → 跳 /workspace
