refactor: simplify order status model — remove DELIVERY_FEE_ADJUSTMENT and PAYMENT_VERIFICATION

- Add deliveryFeeLocked field to Order model
- Remove DELIVERY_FEE_ADJUSTMENT and PAYMENT_VERIFICATION statuses (11→8)
- 3 order paths: delivery+online (locked→unlocked→paid), pickup+online (unlocked→paid), pickup+on_pickup (direct to in_progress)
- Update checkout to use PENDING_PAYMENT + deliveryFeeLocked
- Update payment flow to stay in PENDING_PAYMENT until admin confirms
- Update admin UI to use deliveryFeeLocked instead of status check
- Update client payment UI with new deliveryFeeLocked logic
