Refactor FeignClientSpecification post-processor

Replace raw BeanPostProcessor implementation with GenericBeanPostProcessorAdapter<FeignClientSpecification> to enable type-safe post-processing. Remove AOP target-class lookup and cast, simplify the hook to processAfterInitialization(FeignClientSpecification, String), and tighten the bean-name check to start with "default.". Update imports and JavaDoc accordingly.
