Chats opened from the "Recent" pop-out can't be moved to a group (three-dot menu lacks "Move to group"; drag-and-drop to sidebar groups does nothing)

What's Wrong?

Environment: Claude desktop app [version], [Windows/macOS version], Pro plan

Steps to reproduce:
Have several custom groups in the left sidebar plus chats under "Ungrouped".
Open the "Recent" pop-out (the view for seeing all Unclassified chats) and scroll to a chat.
Click the three dots to the right of the chat, or drag the chat onto a group in the left sidebar.

Expected: The three-dot menu offers "Move to group", and dragging onto a group assigns the chat to it, or at minimum the pop-out gives some route to group assignment.

Actual: The three-dot menu has no "Move to group" option and drag-and-drop does nothing. Right-clicking the same chat in the left sidebar does offer "Move to group" and works.

Impact: For long histories the pop-out is the only practical way to reach older Unclassified chats, so bulk sorting means hunting each chat down in the sidebar first.

Related: #58193 and #69105 (other "Move to group" issues in the desktop sidebar).

What Should Happen?

Expected: The three-dot menu offers "Move to group", and dragging onto a group assigns the chat to it, or at minimum the pop-out gives some route to group assignment.
