test(cdn-logs-report): purge esmock modules in daily-export specs

The agentic-daily-export and referral-daily-export specs created esmock
module mocks on every test but never purged them. Unpurged esmock
registrations leak into the global module registry and cause
nondeterministic cross-file pollution when the full suite runs in a
single process — surfacing in CI as "log.warn is not a function" and
reading ".args" of null in these specs.

Track each esmocked module and esmock.purge() it in afterEach, matching
the existing convention in handler.test.js, cdn-analysis, preflight, and
llmo-config-utils specs.
