changes and correction for admin ->

after changing teacher attendance is should remain as it is for every day do not change again to absent

in main home page of dashboard it should show real time data of number of student and teacher as i added a new teacher is still showing 3 teachers

in payment section give admin option to set by which method did the student paid the fees like upi,card or cash

in payment section add salary option for teacher will tell which teacher got the salary or not

admin is unable to add teacher and student
