Fix AMQP autoconfig on Spring Boot 4.1 / Spring AMQP 4.1

[rammrain]

Closes #112.

Problem

ee.bitweb:spring-core:5.0.0 fails at application-context load under Spring Boot 4.1.0 / Spring AMQP 4.1.0:

BeanCreationException: bean "rabbitListenerContainerFactory" in ee/bitweb/core/amqp/AmqpAutoConfiguration.class
  → factory method "jsaFactory" threw:
    NoClassDefFoundError: org/springframework/amqp/rabbit/listener/ConditionalRejectingErrorHandler$DefaultExceptionStrategy

Spring AMQP 4.1 relocated ConditionalRejectingErrorHandler and FatalExceptionStrategy from org.springframework.amqp.rabbit.listener to org.springframework.amqp.listener. The old types are deprecated forRemoval and the nested DefaultExceptionStrategy no longer resolves at the old coordinates, so a library compiled against them throws at runtime. The new package does not exist in Spring AMQP 4.0.x, so the fix requires a Boot 4.1 baseline.

Changes

• AMQP import relocation — point the two relocated types at org.springframework.amqp.listener in:
  • CoreExceptionStrategy
  • AmqpAutoConfiguration
  • AmqpTraceAwareExceptionHandler (both ConditionalRejectingErrorHandler and FatalExceptionStrategy)
  • TraceIdAmqpAutoConfiguration
• Dependency baseline — all Spring Boot deps 4.0.6 → 4.1.0; spring-webmvc / spring-tx 7.0.7 → 7.0.8 (the Spring Framework version Boot 4.1.0 manages).
• FieldNameResolver migration — the 4.1.0 bump pulls hibernate-validator 9.1.0, which removed the internal NodeImpl / PathImpl / ConstraintViolationImpl types this class relied on. Migrated to the public jakarta.validation.Path / Path.Node API (getName/getKind/getIndex/isInIterable). Behavior preserving.
• Version — 5.0.0 → 5.1.0.

Breaking change

This release drops support for Spring Boot 4.0.x — the relocated AMQP package does not exist there. Consumers must be on Spring Boot 4.1+.
