fix: Suppress Sentry errors from third-party ad scripts

[seer-by-sentry]

Fixes TANSTACK-COM-1FS. The issue was that: Sentry's browserTracingIntegration history instrumentation creates a race condition, causing a third-party blocking script to call an uninitialized function.

• Added a 'beforeSend' hook to the Sentry initialization in 'src/router.tsx'.
• Implemented logic to filter out errors originating from known third-party ad scripts (e.g., Publift Fuse).
• Specifically targets common race condition error messages ("is not a function", "null is not an object", "contextWindow.parent") when associated with ad script filenames or messages.
• Prevents irrelevant third-party ad script errors from being reported to Sentry.
