Set finite connect and read timeouts on the shared RestTemplate.

RestTemplateConfig.restTemplate builds the bean with builder.build() and sets no connect or read timeout. If a downstream service accepts a connection and stops responding, this request can wait without limit. The 504 mapping for timeout exceptions then does not run for that case. The same template serves the other remote calls in this service, so the fix belongs in RestTemplateConfig, not in this endpoint.

at line 91:
Update RestTemplateConfig.restTemplate to configure finite connect and read
timeouts on the shared RestTemplate before building it, so this endpoint and the
service’s other remote calls cannot wait indefinitely.

review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr
