feat: Update Order/CustomOrder models and controllers with event integration

- Add integration fields to Order model: packing_*, courier_*, trello_card_id, qr_token
- Add integration fields to CustomOrder model: packing_*, proof_approved_*, courier_*, trello_card_id, qr_token
- Update Order model fillable array and add relationships (packedBy)
- Update CustomOrder model fillable array, casts, and add relationships (packedBy)
- Add isCustomOrder() method to both models for type checking
- Update OrderController to emit OrderCreated and DepositPaid events on successful payment
- For standard orders: full payment -> prep status, emit events
- For custom orders: deposit -> design status, balance -> printing status, emit respective events
- Add approveProof() method to CustomOrderController (POST /custom-orders/{id}/approve-proof)
- Add requestChanges() method to CustomOrderController (POST /custom-orders/{id}/request-changes)
- Add markBalancePaid() method to CustomOrderController (POST /custom-orders/{id}/pay-balance)
- All new methods emit appropriate events (ProofApproved, ProofRevisionRequested, BalancePaid)
- Add database migration for proof_approved and proof_approved_at fields on custom_orders
- Add routes for new custom order endpoints with UUID binding
- Import all required event classes in both controllers
