`Draft` Course payment

[myniqx]

this is draft. so far, u have to register before join course. we track quota and show to users. users can pre-applicate to courses unless its register date has passed ( last register date is new value to prevent unwanted online payment ) affter pre-application, user can choose pay or inform. 'pay' havent finished. but inform is working. when user choose inform, user have joined that course. and strapi sends a mail (that mail's template is done too) to admin to notify that. and create a new model called Payment beside Donate..

what next: make payment and send email to admins and user. show those payment both users profile page and dashboard.
