refactor: 简化模型管理，移除启用/禁用，优化测试和布局

- 移除供应商/模型启用禁用能力，清理DB schema/migration/API/前端
- 供应商测试改为Base URL连通性+/models探测
- 新增POST /api/models/test模型连接测试
- 新增GET /api/providers/options专用供应商选项接口
- 统一工具栏为ModelsToolbar，参考项目管理布局
- 模型弹窗优化：默认能力、响应式3列标签、并排数值
- 前后端正整数校验、供应商下拉loading/error/empty状态
- 表格列宽统一，操作列/名称列固定宽度
