Documents the new GenAI Settings page (#3590)

Fixes elastic/docs-content-internal/issues/326 by documenting the new
GenAI Settings page within Stack Management. This page introduces new
settings and consolidates existing settings into one place to make it
easier to manage access to AI-powered features in your environment.

It's different in Stack and Serverless, so I used an applies switch to
document the capabilities of both.

+# Manage access to AI Features
+
+This page describes how to use the GenAI Settings page to control access to AI-powered features in your deployments in the following ways:
+
+
+- Manage which AI connectors are available in your environment. 
+- Enable or disable AI Assistant and other AI-powered features in your environment.
+- {applies_to}`stack: ga 9.2` {applies_to}`serverless: unavailable` Specify in which Elastic solutions the `AI Assistant for Observability and Search` and the `AI Assistant for Security` appear.
+
+
+## Requirements
+
+- To access the **GenAI Settings** page, you need the `Actions and connectors: all` or `Actions and connectors: read` [{{kib}} privilege](/deploy-manage/users-roles/cluster-or-deployment-auth/kibana-privileges.md).
+- To modify the settings on this page, you need the `Advanced Settings: all` {{kib}} privilege.
+
+## The GenAI Settings page
+
+To manage these settings, go to the **GenAI Settings** page by using the navigation menu or the [global search field](/explore-analyze/find-and-organize/find-apps-and-objects.md).

+The **GenAI Settings** page has the following settings:
+
+- **Default AI Connector**: Use this setting to specify which connector is selected by default. This affects all AI-powered features, not just AI Assistant. 
+- **Disallow all other connectors**: Enable this setting to prevent connectors other than the default connector specified above from being used in your space. This affects all AI-powered features, not just AI Assistant. 
+- **AI feature visibility**: This button opens the current Space's settings page. Here you can specify which features should appear in your environment, including AI-powered features. 
+- **AI Assistant visibility**: This setting allows you to choose which AI Assistants are available to use and where. You can choose to only show the AI Assistants in their native solutions, in other {{kib}} pages (for example, Discover, Dashboards, and Stack Management), or select **Hide all assistants** to disable AI Assistant throughout {{kib}}.

 Elastic does not store or examine prompts or results used by AI Assistant, or use this data for model training. This includes anything you send the model, such as alert or event data, detection rule configurations, queries, and prompts. However, any data you provide to AI Assistant will be processed by the third-party large language model (LLM) provider you connected to as part of AI Assistant setup.

 ### Get the most from your queries [rag-for-esql]
 
 Elastic AI Assistant allows you to take full advantage of the {{elastic-sec}} platform to improve your security operations. It can help you write an {{esql}} query for a particular use case, or answer general questions about how to use the platform. Its ability to assist you depends on the specificity and detail of your questions. The more context and detail you provide, the more tailored and useful its responses will be.
