Replaces the free-text "Place of Delivery" with a dropdown sourced from a new
admin-managed Delivery Locations list (each = a Company FK + free-text address).
- schema + migration: new DeliveryLocation model (companyId, address, isActive).
- permission: manage_delivery_locations granted to Manager + SuperUser + Admin
(Manager-accessible, not admin-only, per the issue).
- admin screen /admin/delivery-locations: table + Add/Edit dialogs +
activate/deactivate + delete (mirrors /admin/sites); sidebar link under
Administration for Manager/SuperUser/Admin.
- PO forms (new / edit / manager-edit): shared <DeliveryLocationField> native
select populated from active locations, formatted "Company — address".
- PurchaseOrder.placeOfDelivery stays a free-text SNAPSHOT (no FK) — the dropdown
only changes how the value is picked, so export/import/historical POs are
unchanged, and an edit preserves a current value not in the list as a
"(current)" option. Deleting a location is therefore always safe.
- tests: delivery-location CRUD + permission guard (6).
