Saved badge ux is confusing

[fcartegnie]

Saved badge transfert needs to be selected in red through the "play" icon,
then select the gear icon and popup for transfert.
This is way too complex, and buggy because transfert can be activated when no badge is selected.

Should be improved by :
-> Set a global transfert button in preview UI
-> Select source badge with just one tap
-> Select first source badge by default

@mariobehling plz give your suggestions

[fcartegnie]

Transfer button outside the list (before or after the scroll list)
Activates only when preview is selected
