Fix universal links for www domains

[joshheald]

Description

Fixes WOOMOB-3669.

Universal links could open in Safari, because only the bare domains were declared in the app entitlements, without www. This adds both www hosts to every iOS build configuration and re-enables the Universal Link UI tests.

The tests open links through XCUIDevice.shared.system, which runs through iOS Universal Link resolution without depending on Safari UI or accessibility identifiers. This should help address the flakiness of the tests mentioned previously.

Test Steps

1. bundle exec rake mocks
2. Run UniversalLinksTests from the WooCommerceUITests scheme.
3. Confirm the orders link opens order 3337 in the app.
4. Confirm the payments link opens the Payments screen in the app.

Verified on iPad and iPhone using iOS 26.3.1 and 18.6,

@joshheald I noticed the iOS UI tests failed in CI but the reason was POS, not universal links. I retried, twice. POS remained red and universal links green.

There's a flaky label in Buildkite but I think it might be due to the prior flaky behavior because they were green in the three runs.

This should be fixed now, I'll merge trunk here to confirm 👍
