rP519acd9a104e: Fix PHP 8.1 "strlen(null)" exception which blocks Space creation

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 T15340

Thanks for this patch, again

I tested this patch locally. I was able to create a Space, rename a Space, etc., without any nuclear implosion.

Thanks

18	✅ The value `$old` always is NULL at startup, or is a string after a rename. The function `phutil_nonempty_string()` will report any alien type, and that is OK.
