Get Component Usage Flows

Return the flows that would be affected by blocking one component key.

A flow matches when the queried key and any of the flow's stored keys resolve to a shared canonical identity — the same matching rule flow writes and runs enforce. Flows are sorted by name, then id, and truncated to limit; total always reports the full match count. Results may lag flow writes by up to USAGE_SCAN_CACHE_TTL_SECONDS.
