rPeba8012d3e80: Fix PHP 8.1 "strlen(null)" exception which blocks blog rendering

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 T15356

Thanks for this patch

I tested this patch locally, no implosions.

90	✅ I verified the above line The `$post_id` comes from getURIData() that just returns null or a string. The function `phutil_nonempty_string()` will report alien types, and that is OK.
