…d BOM dependencies

…n 4.x to 5.x migration

- Add `ConfigureEventSourcedAnnotationKotlinTest` to verify Kotlin-specific behaviors in migration recipes.
- Introduce `ConvertCommandHandlerConstructorToCompanionObject` recipe to rewrite Kotlin `@CommandHandler` constructors into companion object methods meeting Axon 5.x requirements.
- Add `ConvertCommandHandlerConstructorToCompanionObjectTest` to validate the recipe.
- Add `MigrateAggregateTestFixtureSetupKotlinTest` to confirm Kotlin-compatible test fixture setup migration with proper class literal handling.
- Replace fully qualified references with simple imports for `@CommandHandler` and `EventAppender`.
- Update Kotlin migration recipes to ensure imports are correctly added for compatibility with Axon 5.x.
- Introduce Kotlin upgrade step in migration YAML to support dependency and plugin alignment with Kotlin 2.x.
- Improve handling of `CommandHandler` in companion object transformations to prevent import clashes during migration.
- Introduce `AddEventTagAnnotationKotlinTest` to validate annotation of Kotlin primary constructor parameters.
- Update `AddEventTagAnnotation` recipe to handle Kotlin-specific constructs such as `data class` primary constructors and `val/var` fields.
- Improve annotation handling for Kotlin sources to ensure `@EventTag` is correctly applied and formatted.
- Add test to validate fallback annotation placement for mismatched Kotlin field names.
- Refactor `AddEventTagAnnotation` to properly handle Kotlin `data class` field declaration order.
- Fix `isFirstFieldInClass` implementation to ensure correct field lookup in Kotlin and Java classes.

- Expand annotation rewrites: add `@AggregateRoot` → `@EventSourcedEntity`, and clarify the removal of `@AggregateIdentifier` in favor of `tagKey` + `@EventTag`.
- Document unconditional removal of `@CreationPolicy`, including `AggregateCreationPolicy`, and explain handling for `CREATE_IF_MISSING` and `ALWAYS`.
- Provide additional guidance on lifted `@RoutingKey` and placement of `@EntityCreator` in constructors.

…nTestFixture` cleanup

- Introduce `AddAxonTestFixtureTearDown` recipe to automatically generate an `@AfterEach tearDown()` method calling `fixture.stop()`, ensuring proper lifecycle management for `AxonTestFixture` in JUnit 5 tests.
- Skip classes with existing `@AfterEach` methods or methods named `tearDown` to avoid duplication.
- Limit changes to Java sources only; Kotlin support to be addressed separately.
- Add comprehensive tests to verify correct migration behavior and idempotence.
