Questions	Answers
Branch?	9.0.x
Description?	This PR fixes and extends the handling of attachment entities to support the new /attachments/{attachmentId} API endpoint, currently being developed in PrestaShop/ps_apiresources#105. 🐛 Fixes - Fixed the /attachments/{attachmentId} endpoint by adding the AttachmentId parameter to EditableAttachment and renaming attachmentIdValue → attachmentId in GetAttachmentForEditing. - Ensures correct mapping and retrieval of attachment data for API serialization/deserialization. 🧱 Refactors - EditAttachmentCommand: constructor now accepts int $attachmentId instead of an AttachmentId value object, ensuring compatibility with API Platform. - AddAttachmentCommand and EditAttachmentCommand: added setters setPathName(), setFileSize(), setMimeType(), setOriginalName() to improve flexibility when building commands from uploaded file metadata.
