 * Resolve a booking-create draft into the per-unit quantities and

 * both need. Single source of truth for traveler→unit mapping.
 *
 * Shape branching:
 *   - **Person-priced options** (only `person` units, no `room`):
 *     quantities are derived from traveler assignments (1 adult + 1
 *     child + 1 infant = 3 line items, not "3 x Adult"). Auto-source
 *     travelers are re-derived against the current option's bands.
 *   - **Accommodation options** (any `room` unit): operator-picked
 *     stepper quantities are preserved (1 DBL room is 1 line). Per-
 *     traveler room assignments still update `travelerIndexesByUnitId`
 *     so `booking_item_travelers` rows can be created.
 *
 * Respects assignment sources:
 *   - `none` → the corresponding field stays null
 *   - `manual` → the existing unit is kept when valid for the chosen option
 *   - `auto` → re-derived against current options
