fix: Enhance Sentry error suppression for third-party ad scripts

[seer-by-sentry[bot]]

Fixes TANSTACK-COM-19W. The issue was that: Sentry's History API instrumentation catches third-party script errors before the global window.onerror handler can suppress them.

• Implemented a beforeSend hook in the Sentry configuration.
• The hook filters out errors originating from third-party ad scripts (e.g., Publift Fuse, NoBid).
• Identifies ad script errors by checking specific filenames in stack traces and common error messages.
• Suppresses errors containing messages like 'contextWindow.parent', 'null is not an object', or 'is not a function' when originating from ad scripts.
• Adds debug logging to the console for filtered errors.
