Apps reach every service through Maestro on one port; direct service addressing is no longer a supported deployment, and Maestro has no per-service hostname or host-port route. Replace the maestro/direct modes and the serviceRef lookup with one configured origin and the fixed paths /api/alarm/{action,auth,ws}, defaulting dev builds to 127.0.0.1:8080 through adb reverse. The old mode-specific body wrapping and the direct-mode socket branch go with it.
