fix: Remove duplicate portal_file_detail template causing 404

There were two templates with the same ID 'portal_file_detail':
1. portal_file_detail.xml - Uses 'file' variable (correct)
2. portal_inventory_detail.xml - Uses 'file_folder' variable (duplicate)

The duplicate was causing template conflicts resulting in 404 errors
when accessing /my/inventory/file/<id> routes.

Removed the duplicate template from portal_inventory_detail.xml.
