Reverts split pricing calculation to use outbound-only pricing,
matching BusPro's current behavior where pickup is only charged when
outbound transportation is BUS.
- Use pickup->price directly instead of calculateEffectivePrice()
- PKW+BUS scenario now correctly charges €0 (matches BusPro loophole)
- priceOutbound/priceInbound remain populated for future activation
- Updated documentation with current behavior and future plan
