Subject: [PATCH] Move FQDN trim before validation in submit() method
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The trim operation was happening after validation, which meant
whitespace was counted toward the max:255 validation rule. Now
input is normalized before validation, matching the pattern used
in Application and Service components.
