+ * Repair migration. `SeparateVehicleAvailability1890000000000` is recorded in
+ * public.migrations but the `availability` column is absent on some databases
+ * (recorded-but-not-applied drift). Because the original is already recorded,
+ * TypeORM will not re-run it, so `vehiclesService.findAll` (a query builder that
+ * selects every entity column) 500s with `column "availability" does not exist`.
+ *
+ * This re-adds the column idempotently and backfills. Safe to run everywhere:
+ * `IF NOT EXISTS` makes it a no-op where the column already exists.
