Wires the three broken paths in the cron-driven XL Vask integration:
- runSyncUsage() now calls the revision-aware importUsageLogsWithSummary() on xlvask_usage_logs_o (was a no-op stub; the upstream API was never queried for washes).
- linkImportedUsageLogsToOrders() persists xlvask_potential_order_matches rows so the accept/compare/link/deny UI has data to render.
- When automatic_order_creation_enabled is on and the wash qualifies, falls through to createOrderFromWash() → orders_o::addXLVaskOrder().
- Removes the obsolete TODO in RunXLVaskModuleCron.php.
- Returns linked + orders_created alongside the existing counters so ops can observe the pipeline.
