-- Plan S S23 t9 (2026-05-15) — Wipe ALL workflows (UAT clean slate hoàn toàn)
-- Bro request: "các cái demo quy trình cũ -> xóa hết luôn đi nhé"
-- Current state post-Plan R: 2 V2 ghim + 2 V1 active (đều seed demo cumulative)
-- Backup rollback: C:\Backup\SolutionErp_pre_cleanup_2026-05-15.bak (Plan R)
-- Hậu quả: user KHÔNG tạo được phiếu mới (Workspace Select empty) cho đến khi
-- admin Designer seed workflow mới from scratch.
