Hi Maintainers,

I'd like to work on this issue. I understand the need to emit an EscrowToppedUp event for every escrow top-up so indexers and backend services can track balance changes efficiently without polling storage.

I'll implement the event, ensure quest_id is indexed for filtering, add the required tests, and verify that all acceptance criteria are met.

Thanks for your consideration.
