fix: Add ProveWitness and SyncVault RPCs

The commit message should be:

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.
