[Bug] There is no way to specify host and customOkHttpClient

[rterzman]

🐞 Describe the bug

You can specify host and customOkHttpClient when initializing Pinecone.Builder, but the host parameter is ignored if customOkHttpClient is provided. The condition in the code bypasses host handling:

if (customOkHttpClient != null) {
    apiClient = new ApiClient(customOkHttpClient);
} else {
    apiClient = new ApiClient(buildOkHttpClient(proxyConfig));
    if (host != null && !host.isEmpty()) {
        config.setHost(host);
        apiClient.setBasePath(host);
    }
}

This leads to host being unused when a custom client is passed, even if it was explicitly set.

🧪 Steps to reproduce the issue locally

new Pinecone.Builder("API-KEY")
    .withHost("http://localhost:8080")
    .withOkHttpClient(new OkHttpClient.Builder()
        .addInterceptor(new HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BODY))
        .build())
    .withTlsEnabled(false)
    .build();

🧭 Expected behavior

If host is specified, it should be respected regardless of whether a custom OkHttpClient is used.
