T15296: PHP 8.1 "strlen(null)" exception blocks rendering the Home page

rPf8ae17bb6a1e: Fix PHP 8.1 "strlen(null)" exception which blocks rendering the Home page

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 T15296

Test Plan

Applied this change and Home page rendered in web browser.

Tested locally. No nuclear implosions. Thanks!

29	✅ I debugged `$name` locally with `phlog()` to verify that it only assumes string or null, for example using the Edit Menu Item and similar stuff with fuzzy data. The `phutil_nonempty_string()` will report alien values and that is OK.
