Modification of the site on the unisite engine

The bulletin board on the unisite.org engine needs to be refined. The kernel is written by the owners from scratch, without the use of frameworks.

It is necessary in the functionality of stores, example: https://masele.ru/shop/mediamove

Add additional fields that will be available when creating and editing a store to the user https://disk.yandex.ru/d/A82na2yNZImWUw

Existing fields are marked with green, the rest should be added: https://disk.yandex.ru/d/6SNhR-NzTuoN7w

Important: compliance with deadlines and cleanliness of the code. Hardcode with a breakdown of deadlines is not suitable! In private messages, send the rate per hour, your stack and examples of work.

With a successful experience of cooperation, improvements will be on an ongoing basis.
