新增技能目录重新扫描接口与分页,关掉技能安全扫描的配置开关

- 后端新增 POST /api/skills/reconcile-custom:扫描 custom 目录,把磁盘存在但 DB 无记录的技能登记到调用者名下(published=false),附 4 个单元测试
- 前端技能列表加"重新扫描技能目录"按钮,列表分页每页 10 条
- SkillsConfig 新增 security_scan.enabled(默认 true)用于关闭 LLM 安全扫描;scan_skill_content 在开关关闭时直接放行
- 智能体卡片/对话页长名 truncate 显示 + loading 占位
