feat: 完全移除 API Key 图标功能

彻底删除 API Key 图标功能的所有相关代码：

前端改动：
- 删除 IconPicker.vue 组件文件
- 移除 ApiKeysView.vue 中的图标显示和 updateApiKeyIcon 方法
- 清理 CreateApiKeyModal.vue 中的图标选择器
- 清理 EditApiKeyModal.vue 中的图标选择器
- 移除所有 IconPicker 组件的引用

后端改动：
- 从 apiKeyService.js 中移除 icon 字段更新支持
- 从 admin.js 路由中移除 icon 参数处理和验证逻辑
- 清理创建和更新 API Key 时的 icon 参数

此改动简化了 API Key 管理界面，移除了不必要的图标功能。
