fix: clarify reset-auth-cache failure message

`cj/reset-auth-cache`'s error path read "Failed to clear gpg-agent cache". A user seeing that warning could reasonably think nothing happened. But at that point the Emacs-side caches (auth-source + EPA file handler) have already been cleared. Only the gpg-agent cache failed.

I rewrote the message as "Emacs caches cleared, but failed to clear gpg-agent cache" so the user sees both the partial success and the remaining problem.

The error-path test from the previous commit asserts a substring match on "Failed to clear gpg-agent cache", so it still passes after the rewording.
