Manual subscription creation now shows the right currency and the right variant's price

The manual Create subscription page had two related display bugs. Amounts across the page, including the shipping-price and discount-amount fields you type into, could render with the wrong currency symbol instead of your shop's own currency. And when a product had more than one variant, the plan price shown, and the price attached to the subscription line, could be the price of a different variant than the one you had actually selected.

Both are now fixed. Every amount on the page, including the shipping-price and amount-discount inputs, displays in your shop's currency. The plan price shown, and the price carried onto the subscription line, always match the variant you selected, not another one from the same product.

As part of the same fix, a variant now only offers the selling plans it actually has, so you can no longer pick a plan combination that would have failed when you tried to save the subscription.

What's fixed: manual subscription creation now reflects your shop's currency and the correct variant price throughout. If you enter an amount in the shipping-price or discount fields, it is interpreted as your shop's currency, not converted, so double-check any subscriptions you created manually near this fix if you weren't sure the currency shown was correct.
