Ryan Warner 295a2a7c9f Fix Live Activity compilation and display issues for Mac Catalyst (#4495) ...

## Summary

Follow-up fixes after #4444 merged, addressing issues found during Mac
Catalyst testing:

- **Fix `›` character in Frequent Updates footer** — `.strings` files
don't interpret `\uXXXX` escapes at runtime; replaced with the literal
`›` character
- **Fix Mac Catalyst compilation** — `ActivityKit` APIs
(`ActivityAttributes`, `Activity`, `ActivityUIDismissalPolicy`, etc.)
are marked unavailable on Mac Catalyst even though
`canImport(ActivityKit)` returns true there. Replaced all `#if
canImport(ActivityKit)` and bare `#if os(iOS)` guards around ActivityKit
code with `#if os(iOS) && !targetEnvironment(macCatalyst)`. Files
affected:
  - `HALiveActivityAttributes.swift`
  - `LiveActivityRegistry.swift`
  - `HandlerLiveActivity.swift`
  - `LiveActivitySettingsView.swift`
  - `HADynamicIslandView.swift`
  - `HALockScreenView.swift`
  - `HALiveActivityConfiguration.swift`
  - `Widgets.swift` (three `HALiveActivityConfiguration()` call sites)
- `Environment.swift`, `AppDelegate.swift`, `HAAPI.swift`,
`NotificationsCommandManager.swift`, `SettingsItem.swift` (inline
guards)

## Test plan

- [x] iOS builds and runs
- [x] macOS (Mac Catalyst) builds and launches
- [ ] Live Activities settings entry does not appear on macOS (filtered
by `isTestFlight` + `#available(iOS 17.2, *)`)
- [ ] Live Activities work as expected on iOS TestFlight build
