Nicola Murino ffd87b4878 ssh: fix panic when authority callbacks are nil
Previously, if CertChecker.IsHostAuthority or CertChecker.IsUserAuthority
were left unset, calling CheckHostKey or Authenticate would result in a
nil pointer dereference panic.

This change adds checks to ensure these callbacks are defined before
invocation, returning an error instead of panicking.

This issue was found during a security audit by NCC Group Cryptography
Services, sponsored by Teleport.

Fixes golang/go#79563
Fixes CVE-2026-39835
