edit user profile flow

[wolfhardfehre]

• edit profile is a button in the navbar comparable to sign in
• when edit profile is pressed we open a login overlay and provide a password reset as well
• when we are logged in we open a form to edit the user profile
• this needs a discard button (if changes are made we need to ask if we should save the changes)
• this needs a publish button (maybe log out as well when publishing)
• this needs a delete profile button (marked in red and ask if they really really wanne do it)
• form is pre-filled if user provided content already
