UUID Column change the generation function

Is your feature request related to a problem? Please describe.
Currently we use md5() to generate the uuid column, but since it is not completly safe to use it

Also the identity columns should also be changed

CREATE TABLE IF NOT EXISTS main.auth_clients (
	id                   integer  NOT NULL GENERATED BY DEFAULT AS IDENTITY,
