Finish todo!()s in crates/vrrb_rpc http::routes/accounts.rs

[eureka-cpu]

There are some unimplemented functions that seem to be important to the axum::Router api that either need to be implemented or removed if they are no longer going to be used

async fn create_account() {
    todo!()
}

async fn update_account() {
    todo!()
}

async fn _create_key_router() {
    todo!()
}

async fn _create_token_router() {
    todo!()
}

async fn _get_key() {
    todo!()
}

async fn _create_token() {
    todo!()
}

async fn _update_token() {
    todo!()
}

async fn _get_token() {
    todo!()
}

async fn _delete_token() {
    todo!()
}
