Inventory: One Definition Of Reserved Stock, With A Nightly Repair Pass

Reserved stock was being calculated in more than one place, and those calculations could disagree — the figure on a screen depended on which process wrote it last. There is now a single definition of reserved stock used everywhere, a single place that writes inventory levels, and a nightly reconciliation that repairs any drift it finds. A per-item, per-building level is recorded so the same numbers roll up cleanly across a company. Two cases that made stock look less available than it really was are cleared out along the way, and every scheduled job run now records how long it took, which helps the team spot slow work.
