feat(web): 统一平台管理员判定与 AI 工作台申请预览动作接入

- authUser 抽出 resolveAuthUserAdminFlag，统一 isAdmin 解析（含 superadmin、role_codes、中英文角色名），accessControl 复用同一逻辑
- 登录态、应用外壳路由、系统状态接入统一管理员判定，LoginView 与相关 composable 配套调整
- AI 工作台申请提交改为调用新的 /application-preview-action 接口，草稿保存仍走 orchestrator；预审模型补充重叠冲突提示与阻断判断
- 同步更新 accessControl/api-request/ai 预览动作等前端测试
