Web user support added

[aliaksei-by]

Added support for a web user who only has access to a limited KVM web interface. The default access is web/web.

What is the purpose of this? AI?

func SetAccount(username string, hashedPassword string) error {
	if username == "admin" {
		// check that is really admin
	}

	return SetAccounts(username, hashedPassword)
}

Hi @aliaksei-by ,

Thank you for your contribution and the effort you put into implementing web user support.

We have reviewed this feature request internally. While we understand the utility of having web-based user management, it is currently not a high priority on our development roadmap. At this stage, we are focusing our resources on optimizing core KVM functionalities and stability.

To keep our backlog clean and focused, I will be closing this PR for now. However, we appreciate your work, and we may revisit this idea in the future as the project evolves.

Thanks again!
