This PR makes lot availability exclude quantities already committed on unregistered warehouse and inventory picks, so the same tracked lot is not double-promised to another sales demand. The core change is in codeunit 6501 "Item Tracking Data Collection", with matching W1 and RU regression tests.

The only change since round 6 is in the RU test: CreateLotTrackedItemAtLocation now calls LibraryWarehouse.CreateLocationWithInventoryPostingSetup(Location) instead of CreateLocation(Location). This aligns the RU test setup with the W1 test, which already uses the same helper. The following InventoryPostingSetup.Get guard still prevents duplicate setup, so the change is safe. No production code changed this round.

No new issues found in the latest commits. The single change is a test-only setup alignment (using a location helper that also creates the inventory posting setup) and improves consistency between the RU and W1 tests.

Risk: None added this round. The change touches only RU test setup, not the shipped item tracking logic. The data-integrity path in codeunit 6501 (same item, variant, location, tracked pick lines, positive outstanding quantity, different source) is unchanged and still covered by the W1 and RU tests, so the moved validation still fires at the pick level rather than silently skipping.

Necessity: The bug is valid and important: a lot already allocated on an unregistered pick could otherwise still look available. The test change is a small consistency improvement and keeps the RU location setup on par with W1.
