Undo the full-tree rollback in 6ea1b3d and restore the pre-rollback v1.2.0 code. Preserve the new asset flow rules, abnormal inventory separation, range drilldowns and date picker; adapt the regression test to the restored routes layout.
Use operations signing times and delivery completion statuses; include replacement deliveries in delivery totals with range drilldowns and exports. Separate abnormal vehicles from inventory, add a date range picker, and enable CI for feature/asset-statistics.
