Resolve subscriber disabled status to respective label

• OS: Ubuntu

Description of the bug and steps to reproduce:
Hi,
and first of all thanks for listmonk. I'm still testing it to use it in production soon. Until now it seems really fast and stable. :)
I just encountered one minor UI issue. Instead of showing a disabled label like "Disabled" for disabled subscribers the UI shows, I suppose, a label id subscribers.status.disabled, see screenshot.

That's odd. It doesn't even appear to be in the code? https://github.com/search?q=repo%3Aknadh%2Flistmonk+subscribers.status.disabled&type=code - 0 results.

Ah, this is from the obsolete disabled status from a very early version. It's not used anywhere anymore and subscribers are blocklisted instead of disabled.

Did you set this status via the API as it's not available on the UI.

Yes, I set the status via API as "disabled" is still listed in the API docs, e.g. see here https://listmonk.app/docs/apis/subscribers/#post-apisubscribers

So, I would propose to update API docs and also make the API reject this status. What do you think?
