Bind admin menu globals for PHP admin-page fuzzing

## Problem
The PHP fuzz-suite primitive can fail while loading admin menu files from inside the ability execution trait:

The primitive includes from inside a class method. Included admin files expect and to be normal WordPress globals, but without explicit binding they are local function-scope variables. If is null or inspected before population, menu loading can throw before the primitive can emit structured coverage.

## Expected
should bind the WordPress admin menu globals before including admin menu files, then emit a structured pass/skip/error result instead of throwing.

## Evidence
Observed in Woo admin-page fuzz runs , , and .

## Fix
Implemented in #1412.

Start by reviewing the PHP fuzz-suite ability execution trait and the admin menu files involved in the Woo admin-page fuzz runs. Check the implementation referenced in #1412 and verify that menu loading produces structured pass, skip, or error results instead of throwing.
