I worked on the migration database integrity constraints

Before my contribution, I realized the system was working fine but there were no foreign key integrity constraints in the database design. I worked on the migration schemas, adding the foreign key integrity constraints. I also rearranged the order of the migrations. This provides a better database relationship and schema structure. Test run on a new database. After running the php artisan migrate command, Go to http://localhost/phpmyadmin Click the database > Database designer

Below are screenshots of the old and new database design view

@orajiakuchibuchi Great work! I didn't add foreign key constraint because in some cases, we need to delete a row from a table but it could not be deleted just because of foreign key constrained was integrated.

If you can add some Tests which test of delete actions without being affected by foreign key, I would be confident enough to merge the PR.
