 Just like in #32876, there are several situations where the result of
 `$wpdb->get_var()` is used as is (which is a `string`), and yet data type
 is said to be `int`. The individual situations include `apply_filters()`
 calls, function return values, and class properties, i.e., only ''non-
 local'' usage.

 Please find the attached patch that takes care of that.
 In one case I also adapted two conditionals using a
 former-`string/null`-now-`int`-value.
