feat(ffi): add config server client bindings (#2320)

Add config server client support for the C FFI and Android JNI bindings. Reuse the existing easytier::web_client::run_web_client path and NetworkInstanceManager; OHOS is unchanged. Report successful remote config apply/delete operations through a callback, with one JSON event per affected instance. Keep the config server client and FFI data plane mutually exclusive: once either side is in use, the other side returns an error instead of sharing lifecycle state.
