fix(settings): use in-app StoreKit review for Rate Us

Previously, tapping Rate Us opened App Store URLs (RateUsURL, hardcoded fallback, workspace open). That did not reliably present Apple’s rating UI and diverged from other flows that use SKStoreReviewController.

Changes:
- Implement openRateUsDestination() by calling SKStoreReviewController.requestReview() so Settings matches the native review prompt used elsewhere (e.g. requestAppRatingIfEligible).
- Set userHasRatedDefaultsKey after prompting so automated rating prompts do not overlap with explicit user-initiated taps.
- Remove URL candidate logic and extractAppleAppID helper, which existed only for the old App Store fallback path.
