pub async fn validate_migrations_client<F, Fut, T>(
    module: DynClientModuleInit,
    db_prefix: &str,
    validate: F,
) -> Result<()>
where
    F: Fn(Database, Vec<T::States>, Vec<T::States>) -> Fut,
    Fut: Future<Output = Result<()>>,
    T: ClientModule,

Validates the database migrations for a client module. First applies all database migrations to the module, including the state machine migrations. Then calls the validate function, including the new active_states and inactive_states, and is expected to confirm the database migrations were successful.
