Fix Shared Bridge PR Integration tests

🌟 Feature Request

📝 Description

The new Shared Bridge feature is being added in this PR, and is currently failing a lot of the integration tests (the ones run with zk test i server). They need to be fixed.

This is currently blocked, as completing them requires the contract changes being finished and the SDK being changed according to those changes.
