Changes:
1. employees_list.html - 'Create Profile' button now only visible to staff/superuser
API requires staff/superuser for POST /employees/ (explicit check in create method)
2. department_list.html - Simplified permission check for 'Create Department' button
Changed from: can_create_departments OR perms.employees.add_department OR is_staff
To: is_staff OR is_superuser OR perms.employees.add_department
API uses AdminOrActionOrModelPerms which checks employees.add_department
3. skill_list.html - 'Add Skill' button now requires authentication
API allows any authenticated user to create skills (IsAuthenticated only)
Before:
- Department creation check was redundant with can_create_departments variable
- Skill creation had no check
After:
- All create buttons properly check permissions matching API requirements
- Consistent with feed and documents modules permission patterns
