feat(reservations): detail page with agreement flow + contract mirror

Adds /berth-reservations/[id] with state-aware agreement card (none /
in-flight / completed) and the Generate-agreement entry point that
opens the wizard prefilled. handleDocumentCompleted now mirrors a
signed reservation_agreement onto berth_reservations.contractFileId
so the portal can resolve contracts without joining through documents.
Reservation merge tokens (startDate/endDate/tenureType/termSummary/
signedDate) added to the catalog.
