As an EmbeddedChat developer

I need to: implement keyboard shortcuts for the File Upload Window, where pressing Enter triggers the submission of the file, and pressing Escape closes the modal.

So That: users can quickly interact with the modal using the keyboard, improving usability and efficiency.

Acceptance Criteria

• Pressing the Enter key triggers the submission of the file and prevents the default behavior (such as adding a new line in the text area) when the user is inside the input fields for the filename or description.
• Pressing the Escape key closes the window when the user is inside the input fields for the filename or description.
