fix: tighten values.schema.json validation

- odoo.dbfilter / odoo.db_name: accept a string or the literal false
  (reject true, which is meaningless for these Odoo fields)
- db_replica_port, externalDatabase.port, service.port: bound to 1-65535
  (was minimum 0 with no upper bound)
- rolloutRestart.activeDeadlineSeconds: minimum 1 (k8s JobSpec rejects 0)
