docs: update data access default to enabled (#710)

Updates the data access documentation to reflect that data access is now **enabled by default** for AI agents, rather than being an opt-in feature.

- Reorders the data access modes so "Data access enabled" appears first as the default, with "Metadata-only mode" listed as the alternative
- Updates the info callout and surrounding copy to reflect the new default behavior
- Adjusts the getting started guide to remove the "optional" label from the Data Access section and clarify that it's on by default with the option to disable it per agent

+AI agents offer flexible data access control to balance insights with privacy and security. By default, agents have data access enabled, and you can disable it per agent when you want metadata-only behavior.
 
 ## Data access modes
 
-**Metadata-only mode (default):**
-
-- Agents can see your data structure, field names, and model definitions
-- They can generate appropriate queries and visualizations
-- No actual data values (except for one-row query results) are shared with the agent
-- Perfect for exploring data structure and creating initial analyses

+**Data access enabled (default):**
 
 - Agents receive actual query results in addition to metadata
 - Can provide specific insights, identify trends, and analyze patterns in your data
 - Offers detailed summaries and data-driven recommendations
 - Can search for actual field values to ensure accurate filters when building visualizations
 - Only shares data when explicitly enabled per agent

 <Info>
-  Data access is optional and controlled per agent. When disabled, agents only
-  work with your data model structure and cannot see actual data values. This
-  ensures sensitive information is only shared when you explicitly choose to
-  enable this capability.
