List the actual match rules for one of this account's cost-allocation tag_keys (see list_cost_tags) — which dimension values (or provider-native tag) map to which tag_value, and in what priority order. Rules are evaluated in ascending priority and the first match wins; spend matching no rule falls to "Untagged". Mirrors GET /api/accounts/:accountId/cost-tags/:tagKey/rules. IMPORTANT — a rule is NOT always a single assignment: when its `splits` field is non-null it is an array of {tag_value, weight} with weights summing to 1, and matched spend is divided across those tag_values by weight rather than going wholly to the rule's own tag_value. On a split rule, `tag_value` is only the rule's display label (e.g. "Shared EKS cluster") and no spend is attributed to it. Do not describe a rule with splits as assigning its spend to one team. Note also that some spend may be reallocated after these rules run — see list_cost_tags' redistribute_bucket.
