Fix voting gate to use round status, make eval doc uploads toggleable

Voting check now uses round.status === ROUND_ACTIVE instead of requiring
windowOpenAt/windowCloseAt date range, fixing manual open/reopen scenarios.
Added requireDocumentUpload toggle (default off) to evaluation round config
so rounds reusing prior-round documents don't need file requirements.
