fix(release): unwrap teacup token inputs and correct failure summary

Normalize %touch docker-compose.yml(string=...) wrapped token values in publish composite before
API calls. This prevents malformed Authorization headers under teacup.
Also only print 'Release Published' summary when the publish step succeeds,
and print a failure summary otherwise.
