Adds dokku_service_link task that links/unlinks dokku services to apps, compatible with the upstream ansible-dokku implementation. Includes idempotency via dokku service:linked checks and validation of both service and app existence before attempting link operations. Configures CI Docker daemon with DOCKER_KEEP_DEPRECATED_LEGACY_LINKS_ENV_VARS=1 to support legacy container links in Docker 29+, and adds a runtime skip helper for environments where Docker link support is unavailable.
Verifies the service container is running via docker inspect before linking, checks that REDIS_URL config var is set after link and cleared after unlink, and inspects the service container hostname.
