+-- Apply legacy forces staging data into `forces_present`.
+-- Expected flow before this migration:
+-- 1) Run previous migration that creates `forces_old_import`.
+-- 2) Import old dump rows into `forces_old_import`.
+-- This migration maps old integer IDs into BINARY(16) UUID-style IDs,
+-- then upserts into `forces_present` with `is_active` forced to 1.
