Refining wordPress and integrating with the API payment system

Workreap needs to be refined for WordPress

The list of required improvements:

Integrating the Secure Deal service from the YUKassa payment system to Workreap. Changing the logic of calculations, forming payment forms by API. Disclosure, payouts, checks.
Create a system to monitor and track the time of transactions based on built-in tools. Changing the scenario of creating, completing, cancelling trades in the Workreap theme.
Minor modifications to the built-in chat and the look of the theme.
