This patch updates file-type icons for several media types.

Issue #43797 added file-type icons for attachments, as already done in the repository browser. However, the current logic still shows a generic file icon for the following media types (except for some specific image subtypes):

• audio/*
• image/* (except for image/jpeg and image/png)
• video/*
• text/markdown
• text/x-textile

This patch introduces dedicate icons as follows, improving usability and scanning efficiency when a container has many attachments.

• audio/*: file-music
• image/*: photo (including image/jpeg and image/png)
• video/*: movie
• text/markdown, text/x-textile: file-text (icon already used for text/plain)

The icon mapping logic is shared with the repository browser, so this change also applies there.
