Attachments are not sorted by ordinal

[grantfitzsimmons]

Describe the bug
Currently, attachments are ordered by the attachment ID (e.g. CollectionObjectAttachmentID), in ascending order. This is not configurable via the form meta menu either. This makes it so the only option to reorder attachments is to update the ID behind-the-scenes or for the user to delete and reupload an attachment.

To Reproduce
Steps to reproduce the behavior:

1. Add 3 attachments
2. Update the ordinal value to change the order
3. See that the ordinal is not respected

Happens in both v7.11.4 and v7.12.0.4

Expected behavior
The attachments should be organized by ordinal (as it was in Specify 6).

ORDER BY coa.Ordinal;
