fix: 修复 AILogo 噪音、设置页滚动与供应商批量伪内置脏数据

- AILogo: `custom` 名称为合法兜底场景，不再以 console.error 上报；其余未匹配名称降级为 console.warn
- SettingPage/Model: 双栏加 `min-h-0 overflow-y-auto`，让供应商列表与右侧表单各自可滚动
- ProviderService.add_provider: API 创建一律落到 `type='custom'`，并对同名供应商抛 ValueError，避免再产生伪内置行
- CLAUDE.md: 补充 v2.0.0 子系统（RAG/Chat、可选 Nacos+RabbitMQ、i18n、cookie/transcriber 管理器）
