Fix intent request terminal reason text

Proof: Live request validation showed a not_filled own-request row still displayed the earlier relay-accepted text; the normalizer now prefers terminal outcome reason text and has a regression test for deadline_elapsed_without_settlement.

Assumptions: Terminal request outcome rows are more decisive than submission result text for operator-facing reason copy.

Still fake: Venue-native fill ids and fee-complete realized PnL remain unavailable; completed still depends on durable inventory delta attribution.
