fix: ClassTag context bound compat for Scala 3.8 cross-build (#3073)

Motivation:
In Scala 3.8, [T: ClassTag] context bounds desugar to using clauses,
making explicit ClassTag passing positional-incompatible. Code patterns
like method(args)(ClassTag(clazz)) break when the method uses a context
bound.

Modification:
- Replace explicit ClassTag passing with implicit val ct: ClassTag[T] =
  ClassTag(clazz) followed by method calls that rely on implicit
  resolution, in Behavior.scala, ProducerController.scala,
  WorkPullingProducerController.scala, Topic.scala, ConsistentHash.scala,
  ShardingProducerController.scala, EventSourcedBehaviorTestKit.scala,
  StreamTestKit.scala
- Use .apply() trick in ActorContextSpec.scala: decoration[T].apply(behavior)
  to separate implicit resolution from function application
- Convert context bound [T: ClassTag] to explicit implicit parameter
  (implicit ev: ClassTag[T]) in Supervision.scala
- Merge context bound with separate implicit parameter list in
  PersistencePlugin.scala: (implicit ct: ClassTag[T], ev: PluginProvider[...])
- Refactor ShardedDaemonProcessImpl.scala Java API methods to avoid
  explicit classTag passing
- Fix EventStream.scala secondary constructor formatting

Result:
All ClassTag-dependent code compiles with both Scala 2.13.18 and
Scala 3.8.4. No behavioral changes.

Tests:
Not run - compilation fix, verified by cross-compilation

References:
None - proactive Scala 3.8 forward compatibility
