@RemiBonnet

• On the service list since we changed the copy to "Last operation" everywhere I think we need to update the empty state with "No operations yet" instead of "Never been deployed"

• Minor, but seems like we struggle to retrieve sometimes the profile picture when coming from Google in the user settings. Maybe we need like the navbar a fallback when we have no image/it's not recognized with just the initials? Also could be great in the "Account email" input to have the google icon like we have for github
