## Summary of the Pull Request
Fixes an issue where clicking on a clipboard history item creates a
duplicate entry at the top of the history.
## Problem

When a user clicks on a clipboard history item in the Advanced Paste
clipboard history menu, the item gets duplicated to the top of the
history. This makes it impossible to delete items since clicking the
three-dots menu to delete first duplicates the item.

## Root Cause

The `ClipboardHistory_ItemInvoked` handler was using
`ClipboardHelper.SetTextContent()` and
`ClipboardHelper.SetImageContent()`, which internally call
`Clipboard.SetContentWithOptions()`. This creates a new clipboard
history entry with the same content.

## Solution

Use `Clipboard.SetHistoryItemAsContent(ClipboardHistoryItem)` instead,
which sets the clipboard content from an existing history item without
creating a new history entry.
