Improve logic to display "One time shipping" label on Product Details

[hafizrahman]

Closes: #12785

Description

This PR deals with the "One time shipping" feature in Subscription Product and the way its state is displayed in Product Details screen.

The documentation states this:

Note: For shipping to be charged on initial order, the subscription must not have a free trial or be synchronized to a date in the future. The One-Time Shipping option will be disabled if your product has a free trial or is synchronized.

This PR updates the Android behavior to match iOS:

1. If free trial/future sync is enabled, then we should not display the "One time shipping" description label in Product details, as it is disabled automatically
2. If there is no free trial/future sync and the feature is enabled inside "Shipping", then we want to display the "One time shipping: enabled" description label. If the feature is disabled, we should not display the "One time shipping" description label.
3. Changes in the free trial and toggles should be reflected in the Product Details area correclty.

Steps to reproduce

1. Start creation for Simple Subscription product in the app,
2. Fill in the name, price, then tap Add More Details and select Shipping
3. Fill in just the Weight value, then press back,
4. Ensure the Shipping card in Product Details does not mention "One time shipping",
5. Go back to Shipping and enable One time shipping, then press back,
6. Ensure the Shipping card in Product Details says "One time shipping: Enabled",
7. Tap Subscription free trial and enter a random number (e.g: 3 days), then press back,
8. Check Shipping card and ensure it does not say anything about "One time shipping",
9. Tap Shipping and ensure One Time Shipping toggle is now disabled (this is an existing behavior and not part of this PR, but good to check)

Optionally, also test this with an existing Product. The behavior should be the same.

Testing information

I tested this in an emulator with both new simple subscription product and existing product.

The tests that have been performed

Everything in the list above.

Thank you for clearly explaining the rationale behind the change. LGTM and works as expected. 👍🏻 I’m approving but not merging to give you a chance to consider my suggestion regarding code style.
I also noticed another issue with the "One time shipping" label: #13027. It's reproducable on trunk and outside the scope of this PR.

Thanks! I'll take a look at that issue next.
