refactor: use pattern matching instanceof (Java 16+) (#1721)
Motivation:
Java 16 introduced pattern matching for instanceof, eliminating the need
for explicit casts after type checks.
Modification:
Replace old-style instanceof check with explicit cast in MqttFlowTest.
Result:
Cleaner code without redundant cast expressions.
