Image wrongly imported from clipboard into TextBundle file

[jmbeck15]

Describe the bug
When pasting an image into a TextBundle file, the path is described as (e.g.) textbundle/image-20250125144433623.png rather than copied into assets/. The image is not displayed.

To Reproduce
Steps to reproduce the behavior:

1. Create a TextBundle file and open it with Typora. The "convert to TextBundle" option under Image > "When insert.." works just fine.
2. Drag and drop an image from your computer. This also works just fine; the image appears in the document and is stored under the assets/ path.
3. Now take a screenshot into the clipboard (Ctrl+Shift+Cmd+4 on macOS) and paste it anywhere in the document.
4. Notice that the screenshot doesn't appear, and the path to the image is appended with textbundle/. The binary data is nowhere I can find (certainly it's not in the file).

Expected behavior
The image binary should be named and placed in the assets/ directory in the TextBundle file, and linked accordingly.

Desktop (please complete the following information):

• OS: macOS 15.1.1 (24B91)

Typora Version
Version 1.10.5-dev (7350)

Additional context
The fact that TextBundle is now added to Typora is just fantastic. This really makes my notes much more rich and helpful, so thank you all!
