Builds the exact prefix that network.service's doRequest embeds in the message it throws for
a JSON-RPC error response with the given code — the full thrown message is this prefix
followed by : <error message>.
Exported so the few callers that must classify these thrown errors by message (there is no richer
machine-readable marker for a "method not found" response) derive the format from this single
producer instead of hand-copying the literal. Hand-copied copies silently drift: reformat the
producer and a separate matcher/fixture keeps matching its old string while real errors stop
matching, and the tests stay green. Everything routing through this function stays in lockstep.
Parameters
code: number
The JSON-RPC error code from the error response being classified
Returns string
The exact message prefix doRequest uses for an error response with that code
