[Shopify] Make codeunit 30272 "Shpfy Update Price Source" public

[onbuyuka]

Problem

Partners cannot customize the Shopify connector's price calculation logic because codeunit 30272 "Shpfy Update Price Source" has Access = Internal.

The pricing flow in codeunit 30182 "Shpfy Product Price Calc." publishes OnBeforeCalculateUnitPrice with an IsHandled pattern, which partners can subscribe to. Setting Handled := true lets them fully replace the price calculation. However, replicating the default logic requires BindSubscription on codeunit 30272 to ensure the pricing engine gets the correct currency, VAT, and discount settings from the Shopify Shop configuration. Because 30272 is Internal, partners cannot reference it as a type for Bind/UnbindSubscription.

Fix

Change Access = Internal to Access = Public on codeunit 30272 "Shpfy Update Price Source". One-line change.

Why this is safe

• The codeunit only reads non-sensitive Shop configuration: Currency Code, Allow Line Disc., Prices Including VAT, VAT Bus. Posting Gr. (Price).
• It has EventSubscriberInstance = Manual, so making it public does not auto-activate any subscriptions — partners must explicitly BindSubscription.
• The internal getters on codeunit 30182 (GetCurrencyCode, GetAllowLineDisc, GetPricesIncludingVAT, GetVATBusPostingGroup) remain internal — partners can only use this codeunit indirectly via the existing bind/unbind pattern.
• Only 3 references exist outside its own file: the permission set, a local variable declaration in 30182, and bind/unbind calls in 30182.

Partner scenario

[EventSubscriber(ObjectType::Codeunit, Codeunit::"Shpfy Product Events", 'OnBeforeCalculateUnitPrice', '', true, false)]
local procedure MyPriceCalc(...; var Handled: Boolean)
var
    ShpfyUpdatePriceSource: Codeunit "Shpfy Update Price Source";
begin
    BindSubscription(ShpfyUpdatePriceSource);
    // Replicate CalcPrice logic with their customization
    UnbindSubscription(ShpfyUpdatePriceSource);
    Handled := true;
end;
