Feature #43797
openShow file-type icons instead of paperclip icons in attachment lists
Description
Redmine currently displays a paperclip icon in front of each attachment in containers such as issues and Wiki pages.
In many modern applications, the paperclip icon is mainly used to represent an attachment action (attach a file) or the fact that an object has attachments. It is not commonly used as a generic “file” icon for each item in an attachment list.
This issue proposes to replace the paperclip icon with a file-type icon (PDF, image, zip, text, etc.), so users can quickly understand what kind of files are attached, especially when there are many attachments.
Redmine already shows file-type icons in the repository browser. This patch applies the same approach to attachment lists across Redmine.
