[To Main / DESENG-580] Serialize data for compatibility with new Axios version

[NatSquared]

Issue #: 🎟️ DESENG-580

Description of changes:

• Bugfix: Stop Axios from trying to be a smarty pants and sending data in a format Flask doesn't understand
  • This was preventing the filtering feature from working
  • Directly serialize any metadata filters before the request to avoid Axios's new nested object serialization
  • Deserialize it again on the Flask side
