isOptedOut/addOptOut/removeOptOut used equivalentPhoneNumbers, which is not
symmetric for a 12-digit local outside the 6-9 range vs its 13-digit
counterpart (same root cause already fixed for shared-number detection).
An opt-out registered against one form of such a number silently failed to
block sends to a lead whose number was stored in the other form, on both
the manual send path (reserveOutreachSend) and, independently, in two
inlined checks that bypassed isOptedOut entirely: the last-mile recheck in
campaign-worker.mjs's reserveCampaignQueueSend, and the opt-out NOT EXISTS
clause in campaign-queue.mjs's candidate query. All three now use the
symmetric canonicalPhoneVariants key already introduced for shared-number
overrides, and the worker's last-mile check now calls isOptedOut directly
instead of re-deriving its own number list.
Found via a full-project audit; reproduced and verified before fixing.
