setRefetchCallback was dead code, so on reconnect the queue flushed and Dexie
re-seeded but the open trip's Zustand store was never refreshed — a
collaborator's edits made while we were offline didn't appear until navigating
away and back.
- new tripStore.hydrateActiveTrip(): silent refresh of the active trip's
collaborative state (days/places/packing/todo/budget/reservations/files),
no resetTrip and no isLoading toggle so there's no splash on reconnect
- syncTriggers wires setRefetchCallback to it (WS layer awaits the flush hook
first) and re-hydrates open trips after the online-event syncAll; cleared on
unregister
- websocket exposes getActiveTrips() for the online-event path
- tests: refetch wiring + ordering, silent hydrate without reset/splash
