Restore sweep-test-tiers.sh after intake → editorial-system merge

The weekly test-tier janitor was overlooked when intake/ was merged into
the editorial-system tree on 2026-05-18 (its three sibling smoke-test
scripts moved into intake/scripts/, but sweep was not). Cron on OPi3B
kept invoking the legacy path and failing silently every Sunday since.

Ports the script to intake/scripts/sweep-test-tiers.sh and updates
TEST_REVIEWS to the new editorial-system reviews/test/ path. Cron on
OPi3B repointed (not in repo). Manual catch-up run cleared an 11-dir
backlog (2026-05-26).
