rPab69bcccd982: Fix PHP 8.1 "strlen(null)" exceptions which block adding Dashboard to Project…

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 T15339

Test Plan

Applied these four changes and /dashboard/install/1/project/ finally rendered in web browser.

20	✅ I verified the above line The input string is supposed to be a string, or null. The function `phutil_nonempty_string()` will report alien values, and that is OK.
24	✅ Same as above Also note that `Aphront#getStr()` always return a string, or null.
29	✅ Same as above Note that `getMode()` is populated from `$request->getURIData('modeKey')` that should return a string and defaults to null.
32	✅ Note that `ctype_digit()` is supposed to accept a string
77	✅ Same as above
