Improve avatar uploading / resizing / compressing, remove Fomantic card module (#24653)
Fixes: #8972
Fixes: #24263

And I think it also (partially) fix #24263 (no need to convert) ,
because users could upload any supported image format if it isn't larger
than AVATAR_MAX_ORIGIN_SIZE


The main idea: 

* if the uploaded file size is not larger than AVATAR_MAX_ORIGIN_SIZE,
use the origin
* if the resized size is larger than the origin, use the origin

The only exception: if a WebP image is larger than MaxOriginSize and it
is animated, then current `webp` package can't decode it, so only in
this case it isn't supported. IMO no need to support such case: why a
user would upload a 1MB animated webp as avatar? crazy .....
