Pull Request Overview

This PR adds logic to skip using Fivetran synced dates that are on or before March 9, 2024, likely due to data quality concerns with older Fivetran data in the signature timestamp backfill process.

Key changes:

• Introduced a cutoff date constant for filtering unreliable Fivetran data
• Added validation logic to check if Fivetran timestamps fall before the cutoff
• Modified the snowflakeFix function to skip Fivetran data when timestamps are too old
