Add relation between UserGroup and UserJob

Introduce a ManyToOne relationship between UserGroup and UserJob entities to allow synchronization of group members with corresponding UserJobs. This includes a schema migration to add the `userJob_id` column, associated constraints, and an index, as well as updates to the UserGroup entity with new methods for managing the relationship.
