Migrate `RestTemplate` to `RestClient`

Recipe IDio.moderne.java.spring.boot3.MigrateRestTemplateToRestClient

Artifactio.moderne.recipe:rewrite-spring

Migrates Spring's RestTemplate to the modern RestClient API introduced in Spring Framework 6.1. RestClient provides a fluent, synchronous API that is the recommended approach for new development. This recipe converts constructor calls, type declarations, and common method invocations (getForObject, getForEntity, postForObject, postForEntity, patchForObject, put, delete, headForHeaders, postForLocation, optionsForAllow, exchange) to their RestClient equivalents, and then folds setter-based bean configuration (setErrorHandler, setMessageConverters, setRequestFactory, ...) into the immutable RestClient.Builder API where it is safe to do so. The configuration fold runs after the type change, so it detects setters on the already-retyped RestClient receiver.
