fix(health): 修复 5 角色深度测试发现的权限越权和告警端点缺失

- auth: token_service 查询 role_permissions/user_roles 添加 deleted_at 过滤，
  修复软删除的权限仍被加载到 JWT 的越权漏洞
- health: 新增 GET /health/alerts/{id} 告警详情端点（含 handler + service + 路由）
- web: AlertList 操作按钮增加 active 状态判断，修复按钮不显示
- migration: 新增 000127 清理 doctor 角色多余的 health-data.manage/ai.analysis.manage
