/**
 * Replace an item's routing operations with the ordered list sent. Send every operation the routing
 * should have, in order. Each entry reuses the existing step with the same systemOperationId (the first
 * by order; each step is used once); otherwise a new step is added. On a reused step, omitted fields keep
 * their current values, except leadDays, which becomes 0, and its equipment selection does not change.
 * Steps not in the list are removed; their BOM lines and materials stay on the routing but are no longer
 * tied to a step. Send order on every entry or on none; with none, steps are numbered by the shop's
 * operation-number increment. Read the current steps first with operations/list. Open jobs keep their own
 * copy of the routing and do not change.
