feat: Add ProveWitness and SyncVault RPCs
This change adds two new RPCs to the DID module:
1. ProveWitness: An operation to prove the controller has a valid property using ZK Accumulators.
2. SyncVault: Synchronizes the controller with the Vault Motr DWN WASM Wallet.
These new RPCs allow for more advanced DID management functionality.
