#### Problem description
Submission attachment is shown as downloadable even when it's missing

#### URL of the page
https://test.getodk.cloud/#/projects/149/forms/annotate_default/submissions

#### Steps to reproduce the problem
Make a submission with a missing attachment (for example, in Enketo, annotate an image, scale down the canvas, submit), view the submission table

#### Screenshot

#### Expected behavior
If the submission has state `missingAttachment`, issue HEAD requests for each of the expected attachments and display a red x with a tooltip explanation for any that are missing. See @matthew-white's comment at https://github.com/getodk/central/issues/706#issuecomment-2526604501
