Who knows the CMS / software for teamwork on the required functionality?

Question

CMS

I am looking for a team work system that could include the following features as much as possible:

- knowledge base
- team chat
- kanban board
- spaces (divided into subdivisions)
- a calendar with the ability to mark work shifts, well, or who is at the workplace and who is off, holidays and so on.

with deployment on a personal server and ideally with the ability to integrate with AD, with a one-time payment.

All I find is cloud storage, payment by subscription.
I wanted to organize this on wp, but there one board costs 500 bucks, and there would be no questions if the functionality was like Trello, for example, and there, in fact, and flexibility of settings, there can be no question. For comparison, a wp Divi theme with a built-in page builder for an unlimited number of sites costs 250 bach.

Maybe you can implement this on some other CMS.
