rP8a3e063000c5: Fix PHP 8.1 "strlen(null)" exceptions which block rendering Auth's Customize…

Summary

strlen() was used in Phabricator to check if a generic value is a non-empty string.
This behavior is deprecated since PHP 8.1. Phorge adopts phutil_nonempty_string() as a replacement.

Note: this may highlight other absurd input values that might be worth correcting
instead of just ignoring. If phutil_nonempty_string() throws an exception in your
instance, report it to Phorge to evaluate and fix that specific corner case.

Closes T15325

Test Plan

Applied these three changes and all seven subpages (e.g. /auth/message/user.edit.username/) finally rendered in web browser.

Thanks for your patches again!

Tested locally. No nuclear implosions. I was successfully able to heavily use /auth/message/ with empty/default/custom messages. Everything is OK.

106	✅ I verified with `phlog()` that this variable is always a string or null. The method `phutil_nonempty_string()` will report alien values, and that is OK.
