Restore the array-based signature of PriceCalculatorService::calculate()
to fix the TypeError thrown when PricingController and CustomerOrderController
called it with an array (the previous commit had switched to 4 separate
string params without updating the callers).
- PriceCalculatorService: support multiple input formats for direction
(export|import|Outbound|Inbound) and type (DOC_NORMAL|DOC_ECONOMY|PARCEL|
DOCUMENT|NON DOC) for backward compatibility with admin and customer flows.
- ExchangeRateService: add convertToIrr() for explicit AED→IRR conversion
(was missing but referenced by the calculator).
- PricingController: expand validation rules to accept new shipment types
and a discount_code string (was 'discount' numeric). Add 3-layer exception
handling (422 validation / 400 business / 500 server).
- PriceTestPage: compute volumetric weight from dimensions (IATA: L×W×H/5000),
resolve destination country by direction, and show errors as Filament
notifications instead of crashing.
