Catch RoboflowAPITimeoutError and RoboflowAPIConnectionError in pipeline init (#2285)

Previously these exceptions fell through to the generic Exception handler in
_handle_command, leaving the pipeline subprocess in an unclear state. Now they
surface with explicit error messages and ErrorType.OPERATION_ERROR so operators
can distinguish a network/timeout failure from other init errors.

Related: ROBOFLOW_API_REQUEST_TIMEOUT default added to roboflow-edge build to
prevent indefinite blocking on stale TCP connections after network recovery.
