fix(tui): remove same-id operator gate drop so duplicate asks never strand a resolver

The gate-wire same-id guard ran before timeout, abort, or teardown registration, so a distinct event arriving with an already-live id had its resolve never called on accept, timeout, or dispose. Dedup belongs to the input-required reducer per the plan; gate-wire restores HEAD queue behavior where every event queues and resolves.
