fix: render ValidationMessage in FileUpload, FileUploadWithTag and ImageUpload

[JamalAlabdullah]

Description

Summary2 for FileUpload, FileUploadWithTag, and ImageUpload left out the validation message, so a missing attachment showed in the error list but not under the summary row. The summaries now render that message the same way other fields do.

📝 Walkthrough

Walkthrough

File and image upload summaries retrieve unified validations and pass error-severity validations to their display components. The file summary marks an empty attachment field when errors exist and renders their messages. A test checks the required image validation message.

Changes

Upload summary validation

Layer / File(s)	Summary
File upload validation display src/layout/FileUpload/AttachmentSummaryComponent2.tsx, src/layout/FileUpload/FileUploadTable/FileTableComponent.module.css	The summary marks an empty attachment field when errors exist and renders each error message with its parameters. The stylesheet adds a danger-colored bottom border for the error class.
Image upload validation display src/layout/ImageUpload/ImageUploadSummary2/ImageUploadSummary2.tsx, src/layout/ImageUpload/ImageUploadSummary2/ImageUploadSummary2.test.tsx	The summary passes error-severity validations to SingleValueSummary. A test checks that the required-validation message appears.

each ValidationMessage has a key unique to its validation entry, rather than
using the shared message.key. Keep message.key for the validation message ID and
