fix: append image to FormData before submission in use:enhance

The image upload broke because formData.append() was being called in the
async callback of use:enhance, which runs AFTER the form submission.
Moved the append call to the outer function which runs BEFORE submission.

Also cleaned up debug console.log statements from CardAdd.svelte.
