Integrate Google Tag Gateway toggle to Tag Manager settings screen

[hussain-t]

Feature Description

Currently, Google tag gateway for advertisers (GTG) is available as a centralized setting for Analytics and Ads. Tag Manager users should be able to enable/disable GTG directly from the Tag Manager settings edit screen, providing a more intuitive and module-specific configuration experience while maintaining the centralized GTG setting. This means if GTG is enabled in GTM, it will be enabled in Analytics and Ads and vice versa.

Acceptance criteria

• The Google tag gateway for advertisers Toggle component should be integrated into the Tag Manager module's settings form.
• The toggle should allow users to enable or disable Google tag gateway for advertisers.
• The toggle should default to the current GTG state for existing users.
• The toggle should be wrapped with the Improve your measurement container, similar to the one in the Analytics and Ads modules.
• If either the GTG health check or script access check fails, the toggle should be disabled and grayed out.
• If either the GTG health check or script access check fails, a notice should be displayed below the toggle to inform the user about the server requirements, similar to the one in the Analytics and Ads modules.
• Changes made to the toggle state (on/off) should save the GTG settings in the datastore and persist them on the server.
• The toggle should display server requirements warnings when GTG cannot be enabled.
• If the GTG is enabled in GTM, it should be enabled in Analytics and Ads, and vice versa.
• All the above behaviors should be consistent with the Analytics and Ads modules.
