Note

Adds support for working with content via encoded document IDs and updates UI flows accordingly.

• New overloads in IContentService/ContentService: GetFileContentAsync(string id) and GetItemStreamAsync(string id); ID parsing via DocumentIdentifierHelper
• FullTextContentSearchService now retrieves items using _contentService.GetFileContentAsync(document.Id) instead of manually parsing IDs
• UI: page-detail.js preview opens storefront designer-preview using files-draft.getDocumentId(...); fallback dialog shown when storeUrl is missing
• UI: search index blade fixes and robustness (corrected blade ID, guard nulls, enable button only when index data exists)
• files-draft.service.js: new helpers getDocumentId, getRealFileName (uses draft/real filename logic)
