Sasha teacher dashboard add students

[amak-code]

• Add students page was updated for the creating Classroom process:

  • Header Location was updated (moved to the left)
  • Edit button icon was updated
  • Vertical alignment was updated for the rows
  • Button styles were updated (though I still wait for some design updates)
  • Button logic was updated: now Add and Reset buttons are disabled when the editing process is in progress

• Add Students page was created for the Teacher Dashboard menu when you are in an already created Classroom: classrooms/:classroomId/add_students

  • Continue button was added

  Issues : there are still some inconsistencies in height size between edit row and add row
