Memory Leak: Temporary Files Not Cleaned Up When Pasting Images

[sparrowjack234]

After reviewing the code, I've identified a bug in the clipboard handling implementation. When a user pastes an image from the clipboard, the application creates a temporary PNG file to store the image before inserting it into the document. However, these temporary files are never deleted after they are used, leading to a potential storage leak where temporary files accumulate over time.

Hello,

I am interested in working on this issue as my first contribution to Sugar Labs.
Before starting, I wanted to confirm if this issue is suitable for a beginner.

Thank you for your guidance.

Hello,

I found that a temporary image file created during paste was not closed
or deleted. I added proper closing and cleanup for the temp file.

Please let me know if this approach is correct.

Thank you,
Jyoti
