Cesar Rodas 7146cb8934 Fixed race condition
Bug: https://github.com/cashubtc/cdk/actions/runs/15683152414/job/44190084378?pr=822#step:5:19212

Reason: a race condition between removing proofs while melting and the quote states being updated.

Solution:

1. Error on duplicate proofs
2. Read quote when updating to avoid race conditions and rollbacks

Real solution: A transaction trait in the storage layer. That is coming next
