feat(loyalty): category view mode + mandatory translations

- Add eye icon to expand read-only view of all translations
- View panel shows EN/FR/DE/LB values with "Edit" button to switch
  to edit mode
- All 4 language fields (EN/FR/DE/LB) now mandatory — Save button
  disabled until all are filled (both add and edit forms)
