[Version: 3.13.1] No UI enhancement for inline attachments without attachment compositions

[TiborAdk]

Describe the bug

When using an inline attachment (Attachment) with an entity, and no Attachments composiotion is used elsewhere in the application, the object page of the entity is not enhanced with the facet for an inline attachemt.

(lcoal development using cds watch, likely not limited to local development)

To Reproduce
Steps to reproduce the behavior:

1. Create an entity with an inline attachment.

using {cuid} from '@sap/cds/common';
using {Attachment, Attachments} from '@cap-js/attachments';

namespace sample

entity Invoices : cuid {
  documentNumber : String;
  // annotation causes file upload to fail
  attachment     : Attachment;
  // Uncomment to trigger UI enhancement for attachments
  // attachments    : Composition of many Attachments;
}

annotate Invoices with @(
  UI.LineItem: [
    {Value: attachment_filename},
    {Value: attachment_mimeType}
  ],
  UI.Facets  : [] // Required for plugin to add facets
)

2. Expose the entity through a service definition

service AccountinService {
  @odata.draft.enabled
  entity Invoices as projection on my.Invoices;
}

3. Start development preview (cds watch)
4. Open Fiori preview for AccountingService.Invoices
5. Create a new entity to open the object page
6. UI Facet for inline attachment is not added to the object page

Uncommenting the attachments field leads to both facets for inline and compostion being added.

This is likey caused by the following line in unfoldModel (lib/plugin.js) only checking for sap.attachments.Attachments and not sap.attachments.Attachment as well:

if (!("sap.attachments.Attachments" in csn.definitions)) return

Expected behavior

When using a single inline attachment without another attachments composition in the application, the UI facet for the inline attachments should be added.
