[http-client] Copy Annotations to Generated Clients

[SentryMan]

Given a Client like this:

@Singleton
@Client
public interface ApiClient {

  @Get("/bcVQzeZ.png")
  @Butterfly(kind=MOONLIGHT, status = "it floats down")
  HttpResponse<InputStream> call(@Header("Accept") String accept);
}

The non avaje-http annotations are copied to the generated implementation.

@Generated("avaje-http-client-generator")
@jakarta.inject.Singleton()
public class ApiClientHttpClient implements ApiClient {

  private final HttpClient client;

  public ApiClientHttpClient(HttpClient client) {
    this.client = client;
  }

  // GET /bcVQzeZ.png
  @Override
@com.jojo.javalin.api.aspect.Butterfly(kind=com.jojo.javalin.api.enums.Custom.MOONLIGHT, status = "it floats down")
  public HttpResponse<InputStream> call(String accept) {
    return client.request()
      .header("Accept", accept)
      .path("bcVQzeZ.png")
      .GET()
      .asInputStream();
  }

  public static class Provider implements HttpApiProvider<ApiClient> {
    @Override
    public Class<ApiClient> type() {
      return ApiClient.class;
    }
    @Override
    public ApiClient provide(HttpClient client) {
      return new ApiClientHttpClient(client);
    }
  }
}

Fixes #215
