Implement quote lifecycle investigator

Proof: Adds durable quote lifecycle lookup by quote_id, decision_id, or command_id through the authenticated dashboard API, pins selected Quote lifecycle evidence outside the rolling table, and covers the Awaiting executor follow-up regression with targeted tests.

Assumptions: Existing swap demand, trade decision, execute command, executor result, and quote outcome history rows are sufficient to reconstruct the selected quote lifecycle; this turn stays read-side and does not alter strategy, pricing, limits, arming, signer identity, pair enablement, relay, or executor behavior.

Still fake: Venue-native final fill truth, fee-aware realized PnL, already-pruned historical detail, and the broader quote analytics workbench remain incomplete.
