This strlen() call was preventing a new Phorge instance to be deployed/configured.
Indeed, on a fresh instance, configuration's "base-uri" key may not be defined witch lead to a Runtime Exception.
Using strlen() to check string validity 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.
