Extract duplicated helpers from remote provider files into shared utilities. Split sendRpcMessage into purpose-specific functions. Implement standard nonce-based exchange for re-auth. Provide additional models for more efficient model/symbol/fp/etc using external URLs. This allows us to better handle connection errors, retries and large data packets. Fixes https://gitlab.com/kicad/code/kicad/-/issues/23381
