🐛 fix configure_server_component import

[xvello]

Building a lustre-based application with vite yields the following warning:

[IMPORT_IS_UNDEFINED] Warning: Import `to_server_component_config` will always be undefined because there is no matching export in 'build/dev/javascript/lustre/lustre/component.mjs'
     ╭─[ build/dev/javascript/lustre/lustre/runtime/server/runtime.ffi.mjs:256:18 ]
     │
 256 │   const config = Component.to_server_component_config(app.config);

This PR fixes the outdated import to point to the new function. Build runs without a warning now.
