feat(channels): 管理面板消息日志——chat_messages 加 adapter_id + 配置级/平台/总览三粒度端点

后端：
- 迁移 0007：chat_messages 加 adapter_id 列 + 索引
- history.Message 加 AdapterID；persistToMain/persistIsolated 传适配器名(a.Name())
- channelbridge: 4 个持久化点 + registerSilenced 传 a；light.go registerSilenced 签名加 a
- Store 新增 ListAdapterLog(?adapter=, 不排除主会话)/ListAllLog(adapter_id!='', 总览)；ListPlatformLog 保留
- 新端点 GET /api/v1/admin/channels/messages：?adapter= 配置级 / ?platform= 平台 / 无参=总览，historyMessage 加 adapterId
- 测试：ListAdapterLog/ListAllLog 过滤用例 + 端点粒度用例 + 桥接持久化断言

前端：渠道管理每配置(账号)「消息日志」按钮 + 页顶「适配器总览日志」入口 + ChannelLogPanel 弹窗(总览/配置级)，Miuix 风格，build 绿。
