feat: 全站 Ant Design Pro 风格重构 + 登录守卫与角色门户（issue #131/#134）

- 新增 web/shared：pro.css（AntD 5 设计系统，旧 CSS 变量统一映射 AntD 色板）、
  session.js（后端优先+本地账号降级双轨会话，IAOP_AUTH 兼容层）、
  pro-header.js（全站统一 Pro 导航条：logo/页题/用户角色 Tag/退出）
- 门户 web/index.html：未登录跳登录页（next 回跳），登录后按角色过滤
  可见模块（readonly→驾驶舱/助手/移动端；engineer→+配置台；admin→全部）
- 登录页 auth/login.html 重写为 Ant Design Pro 风格，本地降级模式自动
  播种演示账号（admin/engineer/viewer），保留 OIDC SSO 双轨入口
- user_store.js 新增 verify() + seedDefaults() 默认账号播种
- 六模块页统一接入 pro.css + 统一导航条 + 登录守卫（PRD 8.2）
- 驾驶舱主题 dark→light（Ant Design 5 色板）：renderer.py THEME_TOKENS、
  ti-cl4/resin 模板 theme、告警三级配色对齐 AntD（P0 #ff4d4f/P1 #faad14/
  P2 #1677ff），渲染计划已重编（build_plans.py）
- 验证：core/cockpit 86 单测通过；JS 语法检查通过；静态冒烟全 200
