test(sea): update fakes for statementId / sessionId on the napi surface

The cascade commit that surfaced `statementId` on `SeaNativeStatement` and
`sessionId` on `SeaNativeConnection` (matching the kernel napi binding's
new getters) didn't update the blocking test fakes, breaking compilation.
Add the readonly fields to FakeNativeStatement / FakeNativeConnection
(execution.test.ts) and FakeNativeStatement / FakeMetadataConnection
(metadata.test.ts). The async fakes already carried statementId.
