fix: clear stale nonCurrentRelease regardless of polled review state

Previous fix only cleared stale APPROVED+nonCurrentRelease states when
poll returned mappedState==APPROVED. If the store API returned UNDER_REVIEW
(for the newly-submitted version) while the DB still held a stale
APPROVED+nonCurrentRelease from the old online version, the stale state
was never cleared.

Add universal cleanup: before any mappedState branching, if onlineVersionCode
< submittedCode and the DB entry has nonCurrentRelease/preExisting flags,
immediately clear the store review state.
