feat: Provider 摘要 API 改为服务端分页，支持搜索和筛选

- 后端 /summary 接口新增 page/page_size/search/status/api_format/model_id 参数
- 新增 ProviderSummaryPageResponse 分页响应模型
- 前端 useProviderFilters 从客户端筛选改为构建服务端查询参数
- ProviderManagement 通过 watch queryParams 实现分页/筛选联动，搜索 debounce 300ms
- PriorityManagementDialog 改为对话框打开时自行加载全量 providers
- 其他使用方(StandaloneKeyFormDialog/UserFormDialog/ReplayDialog/ModelManagement)适配新接口
