arrproxy: v0.6.0 self-migrating, drop external migrate Job

Bump arrproxy-api and arrproxy-ui to v0.6.0 and remove the psql migrate Job
plus its migrations ConfigMap. v0.6.0 applies its own schema at startup under
a Postgres advisory lock and holds /readyz until it is current, so the
external hook is dead weight and a drift trap.
