feat: 实现 GlobalModel 别名匹配系统

主要更改:
- GlobalModel 支持 model_aliases 配置，允许使用正则表达式定义别名规则
- Provider Key 的 allowed_models 现在可以通过别名规则匹配 GlobalModel
- 新增 ModelAliasesTab 组件用于管理模型别名配置
- Provider 详情页新增别名映射预览功能，展示 Key 白名单与 GlobalModel 别名的匹配关系
- 路由预览 API 返回 Key 的 allowed_models 信息

安全特性:
- 使用 regex 库的原生超时保护（100ms）防止 ReDoS 攻击
- 别名规则数量限制（50 条/模型）和长度限制（200 字符）
- 别名映射预览 API 添加超时保护和结果截断

其他改进:
- GlobalModel 更新/删除时使用行级锁防止并发竞态
- 缓存失效逻辑优化，支持异步清理和正则缓存清空
- 路由 Tab 布局重构，使用 flexbox 替代绝对定位
