feat: M1 高级传输参数（P0）

- store: Local 增加 useEncryption/useCompression/bandwidthLimit/poolCount/metadatas/annotations；Remote 增加 transportProtocol/transportTls/transportPool/transportTlsServerName；新增 migrate() ALTER TABLE 迁移旧库

- render: 输出 transport 段（protocol/tls/poolCount）与 proxy 高级字段；补 TestRenderTransportAdvanced/OmittedWhenEmpty

- main: renderRemote 闭包透传 M1 字段到 render.Proxy

- web: LocalNode/RemoteNode 折叠高级区表单，types.ts 接口扩展

- 验证：go test 全绿、vue-tsc/build 通过、端到端 PUT canvas→frpc JSON 输出完整
