Subject: [PATCH] BUG: Add null check for $pmpro_level in
 pmproga4_checkout_events()

Fixes a PHP warning 'Attempt to read property on null' thrown when
$pmpro_level is not populated on the checkout page. This can happen
when bots, crawlers, or redirects hit the checkout URL without a
valid level context. Added an early return guard to prevent accessing
properties on a null object.
