Set where materials go by default, per department

Company settings has a new Department default locations section. For each department, set the default receiving, staging, output and ship-from locations, and a fallback location for everything else. A user can still select a different location for a single transaction; that never changes these defaults.

A Location rules section sets the priority order each transaction type uses to find a location when none is selected: receiving, material usage, production output, pick lists and outbound deliveries. Raise or lower a rule, stop using it, or add one that isn't used yet. For example, a part can go to its own default location before the stage's location, or to wherever the order's other parts went. Until you change it, each type uses a default order. Receive mode and the pick screen show the location these rules choose, so what you see is where the material goes.

Every department now has a fallback location. If you don't set one, it's the department's first top-level location, as the Locations page lists them, skipping staging and in-transit spots, so recording usage or produced parts no longer fails because a material has no default location. Stock drawn from there without any on hand shows as negative until it's counted or received, which makes it easy to find.

When nobody picks a location, materials are now drawn from the location with the most stock, not the first one alphabetically, and never from another staging or in-transit spot. An emptied staging spot no longer hides stock on the shelf. Material that sits at the stage's own location is used first.

New inbound deliveries start at the department's default receiving location, new outbound deliveries start from its default ship-from location, and new pick lists start with its default staging location.
