Allegro message filters work again, with a clear unavailable-thread message

What changed?

Filters for starred threads and threads marked for a later reply are working again. If Allegro no longer makes a saved conversation available, Kiero OMS shows a clear message instead of a generic error.

Benefit

You can return to important threads without a database query error. If Allegro has removed or stopped exposing a conversation, you immediately know that the thread is unavailable at the provider; the local record is not automatically deleted.

How to use it

In Messages, use the starred or reply-later filters. Open a selected thread as usual. If Allegro reports that the thread does not exist, you will see an unavailable-thread message.

Important limitations

The message does not explain why Allegro removed or stopped exposing the conversation, and it cannot restore the thread content. The filter queries were checked in production; clicking the mark toggles in the interface still needs a separate test.
