feat(killinchu): fold in FULL vessels context — add 4 missing seed-data datasets (event-logs, fleets, maintenance-logs, shipment-records) as static FLEET endpoints + 2 new FLEET tabs (Ops & Maintenance Logs, Voyages & Fleets). Drones stay front-and-center; vessels additive. Sample fleet dataset — not a live AIS/class-society feed.

Wire FLEET (Vessels) + Voyage Risk; graceful consensus (amaru-independent); fix Living Organism load flash
