[FIX] gamification: several layout issues

1/ ISSUES WITH BADGES:
Go to menu Employees > Badges > Select any Badge from kanban View.
Click on "GRANT THIS BADGE" button.
- When you grant a badge, the description field is not at the right place.
  It should be below the employee field
- Badges Form View: "Granted Employees" should be a stat button with a counter
- Badges form view is broken, field label/values are not at right place

2/ ISSUES WITH CHALLENGES:
Go to menu Employees > Challenges
Challenges Kanban View
- Image Avatars are too big, make it smaller.
- Challenges Form View > Advanced Options : fields Report frequency, Report Template
  and Send a Copy to are ugly
