run proto scripts (#460)

This pull request updates the DKIM module's API to simplify the query
interface and remove redundant proof verification methods. The main
changes are the removal of the `ProofVerify` gRPC method and its
associated code, as well as some additions and clarifications to the
query request structures.

### API interface simplification

* Removed the `ProofVerify` method from the `Query` gRPC service,
including its method definition, handler, and references in both the
client and server interfaces (`query_grpc.pb.go`).

### Request structure improvements

* Added detailed fields to the `QueryAuthenticateRequest` struct,
including `tx_bytes`, `email_hash`, `proof`, `public_inputs`, and
`allowed_email_hosts` to support more comprehensive zk proof
verification requests (`query.pulsar.go`).

### Genesis state documentation

* Added a comment clarifying that `dkim_pubkeys` in the `GenesisState`
struct stores the list of active DKIM public keys (`genesis.pulsar.go`).

### Protobuf descriptor updates

* Updated the protobuf descriptors and method indices to reflect the
removal of `ProofVerify` and the changes to the available methods
(`query.pulsar.go`).

These changes streamline the DKIM query API, removing unnecessary
duplication and making the authentication request structure more
explicit and robust.
