feat(server): Allow activating non-admin user with server license

[stephen304]

Here's a small suggestion to allow non-admin users to activate their user account with a server license. This would allow a user to move between a self-hosted server to server managed by someone else and not need to buy an individual user license if they already have a server license.

Only a few changes:

• Change user endpoint to accept both server/client licenses
• Change web logic so that the behavior for admins stays the same (server license -> server service, invididual license -> user service), but for non-admins both individual and server licenses go to the user service (currently entering a server license as a non-admin causes web to try to activate the server through the server endpoint, which of course fails due to not being an admin)
• Added test for user endpoint to accept server licenses

This sounds logical to me, thanks!

Hmmm it appears I made an oversight in the frontend part, the user.isAdmin is not working right so it only uses the user activation endpoint even when you are admin and use a server key. It appears isAdmin is on the object (UserAdminResponseDto) on the definition but linting says otherwise, so I'm not sure how to make this work.

Edit: I think I found the right way to get the user, tested with a server key on a non-admin and with admin. It activated the user account when non-admin and activated the server when used as admin.
