…M\Support namespace

In PPOM 34.0.1, the wholesale-pricing helper was refactored into the
PPOM\Support namespace (src/Support/Helpers.php), but the external
WWP_Wholesale_Roles, WWP_Wholesale_Prices, and WWP_Helper_Functions
class references were left without global `\` qualifiers. PHP then
looked for them under PPOM\Support\ and threw:
  "Class PPOM\Support\WWP_Wholesale_Roles not found"

Fix: prefix all three external class names with `\` in
get_product_price() and get_product_regular_price() so PHP resolves
them in the global namespace regardless of calling namespace.

Add regression tests with in-file global stubs for the WWP classes
to confirm no fatal occurs and the wholesale price is used when
available.
