fix: Enhance ad network error suppression to include Adform

[seer-by-sentry[bot]]

Fixes TANSTACK-COM-19X. The issue was that: Adform script's cross-origin window.top.document access fails in iOS Safari, triggering a TypeError not caught by existing suppressions.

• Generalized error suppression for ad network scripts (e.g., Publift Fuse, Adform) in Gam.tsx.
• Added adform.net to the list of sources for which cross-origin errors are suppressed in the global window.onerror handler.
• Updated comments to reflect the broader scope of ad network error suppression.
