Pull Request Overview

This PR adds re-randomization functionality to transaction inputs in the FHE computation system. The key changes include modifying the scheduler to support transaction-level re-randomization, updating database schemas to track allowed handles more efficiently, and adding cryptographic domain separators for secure re-randomization.

• Added re-randomization of transaction inputs using cryptographic domain separators
• Refactored database handling to track allowed handles at the computation level instead of separate tables
• Updated scheduler to process transactions with re-randomized inputs and improved error handling

Looks generally ok for the rerand part, some comments and domain separators to update

the parameter mixing is not the right thing to do, though I don't know what purpose those parameters serve

I haven't followed all the decisions made on how to implement it, but I can't see an issue right now. Approving it with the caveat that I might have missed issues.
