test(opengateway): add Macaron regression coverage + picker expectation

Adds macaron.test.ts (descriptor capabilities/limits, gateway catalog
apiName/modelDescriptorId wiring, runtime limits — tencent.test.ts
pattern) and includes mindai/macaron-v1-tall in the /model picker's
expected opengateway option list.
