feat(xingbang): 兴邦金租 AI 评审平台前端页面(深色商务风)

- 独立路由 /xingbang: 兴邦评审工作台
- 五智能体流水线可视化(状态动画: 排队/运行/成功/失败)
- 评审任务表单(客户/金额/租赁物) + SSE 实时进度
- 审批结论卡片(五智能体产出) + 自进化洞察面板
- Navbar 加兴邦评审入口, 支持返回聊天
- 深色商务风 (渐变背景/玻璃拟态/金蓝主题)
- api.ts 新增兴邦 API 调用(workflow/evolution/trajectories)

前端已在 next dev 验证渲染 OK, 后端 API 就绪(7条轨迹样本)
