Niaz Sagor 8da6d98439 Show placeholder for broken activity images (#2769)
Hello, I noticed that there are several image URLs that fail to load on
the Activities screen of the compass_app. The image shows the default
error widget right now.
This PR proposes to display a placeholder with a "broken image" icon
instead of the default error widget. This provides better visual
feedback to the user.

Current:
<img width="354" height="275" alt="image"
src="https://github.com/user-attachments/assets/3688e1a0-c36d-40ef-9474-001e3576d55a"
/>

After fix:
<img width="354" height="275" alt="image"
src="https://github.com/user-attachments/assets/0f853596-6b9c-4b82-b646-8a3cf01c6ad0"
/>

@ericwindmill, please take a look and see if it is appropriate.
