Share trust center test lookup and activation helpers

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.
