WebSockets Next: follow the rule of Quarkus REST for Transactional annotation

[mkouba]

Description

It seems that Quarkus REST has a specific rule for @Transactional: "If a method or class is annotated with jakarta.transaction.Transactional then it will also be treated as a blocking method. This is because JTA is a blocking technology, and is generally used with other blocking technology such as Hibernate and JDBC.".
