fix: prepend context-path to TsfApiMetadataGrapher OpenAPI paths

Apply the same context-path fix to TsfApiMetadataGrapher as was done
for PolarisContractReporter. When server.servlet.context-path or
spring.webflux.base-path is configured, the OpenAPI paths are now
prefixed before serialization to the $api_metas system property.
