Direct truck-to-train export cargo skips the warehouse, so the existing
carriage acceptance sheet ready notice (fired on warehouse receive)
never reached these bookings. Their handover moment is the load itself.
Extract notifyCarriageAcceptanceReady into a shared notifications util
(was private to WarehouseInventoryService) and call it from
BookingJourneyService.loadBooking for EXPORT + DIRECT_TO_TRAIN bookings,
right after the GRN gate, before the load transaction proceeds.
Replaces the owner/general-manager/PoA trio with a single identity whose
subject is the PoA when the company declares one and the owner otherwise.
- Drop the general manager everywhere: entity columns, DTOs, required-field
list, self-service attributes, gm* identity handling.
- New explicit poaDeclared answer ("yes"/"no") replaces poaSameAsOwner. A
DARS delegation letter is required iff it is "yes"; a freight forwarder is
forced to "yes" server-side and gets no waiver.
- Owner name/email/phone become typeable and required, prefilled from the
eTrade lookup, never falling back to the authenticated account.
- Store eTrade's manager separately (etradeManagerName/Phone) and expose
ownerMatchesEtrade so backoffice compares the asserted owner against the
licence instead of against itself.
- Foreign companies satisfy the identity with Fayda or a passport number, on
whichever subject is verifying (poaPassportNumber added).
- Write companies.email/phone from the owner unconditionally, so a company
without a Fayda-verified owner still has a notification address.
