The Card Place iOS gets ready for the App Store: listing in the repo, privacy manifest, screenshots by script

[kellylford]

Part of #202. The list of what was missing is in the comment on the issue.

What this adds

• The store listing, as files to review. thecardplace/ios/store/en-US/ has one text file per field: description, keywords, subtitle, promotional text, and the notes for App Review. store/app-store.json has the rest: copyright, manual release, the category (Games, with Card and Board as subcategories), URLs, content rights, the review contact, the age rating answers (all None, so 4+), Accessibility Nutrition Labels, and price.
• scripts/wire-appstore.py compares the listing in the repo with what App Store Connect has, and prints every difference. It only writes with --apply. Price and availability also need --set-price. --publish-accessibility publishes the accessibility labels, which Apple only allows once the app is on the store.
• A privacy manifest, PrivacyInfo.xcprivacy: no tracking, no data collected, and UserDefaults declared (reason CA92.1) for the settings.
• Screenshots by script. scripts/take-screenshots.sh runs the UI tests on a 6.9" iPhone and a 13" iPad simulator and keeps the screenshots they take in each game. scripts/upload-screenshots.py replaces each device's set.
• thecardplace/privacy.html, a privacy policy page. It and the Card Place page's footer give support@theideaplace.net.
• American spelling in everything a player or reader sees: the app's hub and help text, the store text, the Card Place and euchre pages, and the READMEs. Code comments and names such as sameColour are unchanged. The multiplayer forks' READMEs are left for a separate branch, because the fork guard refuses a branch that changes both a stable game and its fork.
• The app's own text changed, so this is build 5.
• RELEASE.md gets an App Store release section.
• Two test fixes found while taking screenshots. The euchre UI test failed whenever the player was dealer and a computer ordered the card up straight away. And screenshots now wait for a changing label to finish its cross-fade.

Done in App Store Connect, with Kelly's go

• Build 5 uploaded, processed, and chosen for version 1.0.
• All of the listing written. A second pass of wire-appstore.py finds nothing left to change.
• Free, in all 175 territories and any Apple adds later.
• 12 screenshots uploaded; all processed.
• Accessibility labels saved as drafts. They're published after release.

Left for Kelly

• Merge this PR. That publishes the privacy page the listing points at, so it has to happen before submitting.
• On the App Store Connect website, App Privacy: "Data Not Collected", then Publish.
• Add for Review, then Submit.

Testing

• swift test for the engines: no failures.
• take-screenshots.sh on both devices runs every UI test; they all passed on the iPhone 17 Pro Max and iPad Pro 13" (M5) simulators. All twelve screenshots are the required sizes. I looked at them, including the hub's "its color partner".
• The web game checks all pass on this PR.

Independent review by a separate agent: no blocking bugs. Fixed from it: contact details read from outside the repo; screenshot sets replaced within Apple's 10-per-set limit and only after the new ones finish processing (run for real on both sets); price and availability skipped when already set; euchre later-hand flake; screenshot script runtime sort and status-bar trap; privacy page date and browser-settings note. A second pass of the reviewer confirmed the fixes. All checks pass.
