[MBL-1605] Display Estimated Shipping on Rewards and Add-Ons

[scottkicks]

📲 What

I recommend reviewing this commit by commit

Displays estimated shipping range, if there are any set, on reward card and add-on card views.

🤔 Why

See jira ticket

🛠 How

Updates RewardCardView and RewardAddOnView
Uses the same styling as the other sections of the cards.

ShippingRule structs contain the newly exposed estimatedMin and estimatedMax values that are set in the project config.
Since a reward can have multiple ShippingRules, we need to pass the ShippingRule that is selected in the location dropdown to the RewardCardView so that we can determine which ShippingRule info to display.

This only applies to rewards cards because we already pass in the relevant ShippingRule to the AddOns screen.

From there it's just getting the new UI elements in place and making sure this is only shown when the feature flag is on and when there is actually estimated shipping values to show.

• Estimated shipping isn't required by creators so if there is none, we don't show anything.

✅ Acceptance criteria

• Estimated shipping is shown on reward cards and addon cards when feature flag is on an values are set

⏰ TODO

• We'll get the hardcoded strings translated and updated later before release.

FYI this has some extra commits that will be on main by now. Formatting that Ingerid fixed + exposing estimated shipping properties stuff that I did. These should be cleaned up once main is up to date.

Looks pretty good but please make sure you handle the "estimated min and max are equal" case and add snapshot tests for this before submitting. Marking this as approved because I don't think I need to re-review it, but please lmk if you want me to take a look at any changes!

Nit: Might be helpful to tag a ticket number here to make it easier to find all the strings once translations are ready

[ifosli]

I think this needs to check if formattedMin == formattedMax and just use ex About $\(formattedMin)$ if they're equal. Will you fix and maybe add tests for this function specifically, especially if it's not already covered by other tests?

[ifosli]

Can you add snapshot tests to this where the estimated shipping shows? I think one where the min and max are different and a different one where they're equal should cover it, but feel free to cover other edge cases if I'm missing something!
