fix(dash): gate verify_rotated_quorums == false storage on all-verified

The `else if` branch in `feed_qr_info` skipped verification but still wrote into `rotated_quorums_per_cycle` whenever `already_fully_verified` was false. That contradicted the documented invariant ("a cycle is only stored when every entry is `Verified`") and could poison IS-lock BLS verification with unverified `quorum_public_key` values.

Mirror the verified-only gate from the `verify_rotated_quorums == true` path: only store when every entry is `Verified` (which can still hold via cache hits from `known_qualified_quorum_entry`).
