With {ART} in the raw material number format (default {ART}-{YYYY}-{SEQ:4}),
beeswax and propolis each count on their own: WA-2026-0001, PR-2026-0001.
Counters live in the new AutomationSequence table (one row per rule and
scope). Without {ART} the rule keeps its single shared counter, since
separate counters behind one prefix would hand out duplicate numbers.
Resetting a rule clears all of its counters.
