dm: delegate resolveProfileSummaryForPubkey to helper (fix moderation UI crash)

ProfileModerationController calls dmController.resolveProfileSummaryForPubkey
when rendering moderation overrides, but the method lives on the DM helper and
the controller didn't delegate it — so opening the profile modal's moderation
settings threw an uncaught "is not a function". Add the helper delegation
(createCompactProfileSummary right after it was already delegated). Covered by
the delegation regression test.
