This commit allows avatar that would not be squared to be rendered with
a correct aspect ratio inside Forum.
Before these changes, if the user avatar was not uploaded in a squared
size, it would be stretched while being rendered inside the forum UI.
To solve this issue, we simply add the `o_object_fit_cover` class to
these avatars, ensuring they are well rendered.
We also changed the resolution to 128x128, to provide a better render.
