feat(kiro): Add Kiro OAuth login entry and auth file filter in Web UI

为Kiro供应商添加WEB UI OAuth登录入口和认证文件过滤器

## Changes / 更改内容

### Frontend / 前端 (management.html)
- Add Kiro OAuth card UI with support for AWS Builder ID, Google, and GitHub login methods
- 添加Kiro OAuth卡片UI，支持AWS Builder ID、Google和GitHub三种登录方式
- Add i18n translations for Kiro OAuth (Chinese and English)
- 添加Kiro OAuth的中英文国际化翻译
- Add Kiro filter button in auth files management page
- 在认证文件管理页面添加Kiro过滤按钮
- Implement JavaScript methods: startKiroOAuth(), openKiroLink(), copyKiroLink(), copyKiroDeviceCode(), startKiroOAuthPolling(), resetKiroOAuthUI()
- 实现JavaScript方法：startKiroOAuth()、openKiroLink()、copyKiroLink()、copyKiroDeviceCode()、startKiroOAuthPolling()、resetKiroOAuthUI()

### Backend / 后端
- Add /kiro-auth-url endpoint for Kiro OAuth authentication (auth_files.go)
- 添加/kiro-auth-url端点用于Kiro OAuth认证 (auth_files.go)
- Fix GetAuthStatus() to correctly parse device_code and auth_url status
- 修复GetAuthStatus()以正确解析device_code和auth_url状态
- Change status delimiter from ':' to '|' to avoid URL parsing issues
- 将状态分隔符从':'改为'|'以避免URL解析问题
- Export CreateToken method in social_auth.go
- 在social_auth.go中导出CreateToken方法
- Register Kiro OAuth routes in server.go
- 在server.go中注册Kiro OAuth路由
