Fixed bugs (laravel)

There is a system in laravel for collecting, recording, payment and issuance of orders for sales of digital products (gifs)

Bugs occurred in the following locations:
- Payment (qiwi accept payment check po number)

- Interaction with Yandex disk (the script parses Yandex disk, finds the order number of the. gif file with the desired name, pulls it from the disk to the server and displays to the client)

- Splitting the gif (when the client downloads the gif-well, the script divides it into 2 parts, and packages them in the archive)

Scripts written, and worked up to a point. Further, according to misunderstood reasons and went to bugs

A more detailed TOR will be sent to BOS
