feat: 新增模型管理功能（供应商 + 模型 CRUD）

- 新增 providers/models 数据库表、迁移和数据访问层
- 新增 15 个后端 API 路由（供应商/模型 CRUD + 连通性测试）
- 新增 AI 服务层（registry.ts: buildProviderRegistry + testProviderConnection）
- 新增前端模型管理页面（Tabs: 供应商/模型，含表格、表单、工具栏）
- 新增前端 hooks（use-providers, use-models）
- 新增共享类型和 MODEL_CAPABILITIES 常量
- 新增 10 个测试文件（66 个测试用例，4 个因 bun test ESM 兼容问题待修复）
- 更新开发文档（architecture, backend, frontend）
- 附带 apply-review 修复：统一错误响应、提取共享常量、清理重复测试

注意：registry.test.ts 中 4 个测试因 bun test 无法解析
createProviderRegistry ESM 导出而失败，详情见 context.md
