Two files declared activateTrustCenter in package trust_test, so the package no longer compiled, and the trust-center lookup plus activation logic was duplicated four ways across the suite. Move lookupTrustCenterID and activateTrustCenter into a shared helpers_test.go and route every call site through them, dropping the inline copies in the logo and report-export tests.
