by devpabloggtsk68: Adds JPA support for user favorite stories
This commit adds the JPA mapping needed to support users having a list
of favorite microstories. It introduces a bidirectional @ManyToMany
relationship between User and Story, backed by the new user_favorites
join table. Domain entities were updated with helper methods to manage
the association and expose unmodifiable views. Database DDL/DML scripts
and domain tests were updated accordingly. DBUnit dataset was extended
to include favorite stories.
