Unable to delete chats in Desktop (windows)

**Describe the bug**

Unable to delete past chats in 1.47.0 Windows Desktop app.

As per #9701, I have tried deleting chats by going to Session History.

There are supposed to be actions, including a delete button, when you hover over chats.

But I do not see any actions at all (see screenshot).

**Please provide the following information**
- **OS & Arch:** Windows 11
- **Interface:** Desktop UI
- **Version:** 1.47.0
- **Extensions enabled:** Standard Only
- **Provider & Model:** Various

Look at the desktop UI code for the Session History component, likely in a frontend crate or module. The hover actions are missing; check the rendering logic and event handling for chat items. Run the desktop app locally to reproduce the issue, then inspect the UI layer to see why the delete button is not appearing.
