feat(warehouse): fetch all PAID bookings in one call, classified IMPORT/EXPORT by route

- eligibleBookings(direction?) now returns all import+export bookings when direction omitted
  (DOMESTIC excluded); per-direction filter preserved for backward compatibility
- GET /warehouse-inventory/eligible-bookings (no query) returns the combined set
- Frontend: single shared useEligibleBookings() query; both Receive tabs filter client-side
  by route-derived direction, so only one HTTP request fires
