Folder navigation in ListDrawer/upload picker when folders: true is enabled on collection

[DaniilGiz]

Feature Request

Problem

When folders: true is set on a collection (e.g., Media), the admin list view correctly shows folder navigation via the BrowseByFolder view. However, when selecting a document via the ListDrawer (upload/relationship field picker), the drawer always renders viewType: 'list' (hardcoded in handleServerFunction.js), ignoring folder structure entirely.

This means users with 50+ media items organized into folders still have to scroll through a flat, unfiltered list in the picker.

Expected Behavior

The ListDrawer should support folder navigation for collections with folders: true, giving users the ability to browse into a folder and select from a smaller, organized set of documents — the same experience as the full-page list view.

Current Behavior

handleServerFunction.js hardcodes viewType: 'list', so the BrowseByFolder component is never rendered inside the drawer.
