Fix macOS distribution entitlements and Sparkle beta defaults

- Add macOS-specific entitlements via CODE_SIGN_ENTITLEMENTS[sdk=macosx*]:
  the iOS aps-environment key is silently dropped from macOS exports,
  leaving distribution builds without a push entitlement (no CloudKit
  sync pushes). Release now uses Yattee-macOS.entitlements with
  com.apple.developer.aps-environment = production.
- Release-DeveloperID uses Yattee-macOS-DeveloperID.entitlements, adding
  the Sparkle mach-lookup temporary exceptions (-spks/-spki) required
  for the updater to install in a sandboxed app.
- Default Sparkle updater to the beta channel while only beta releases
  exist, so testers receive updates without toggling Advanced settings.
- Set NSHumanReadableCopyright for the app target.
