Weighting inside admin

[felipeelia]

Description of the Change

This is a follow-up of #2267. Even with Protected Content enabled, weighting should be applied only on the front end.

Developers wanting to change that behavior can use this snippet:

add_filter(
	'ep_is_integrated_request',
	function( $is_integrated, $context ) {
		return ( 'weighting' === $context ) ? true : $is_integrated;
	},
	10,
	2
);
