Release 1.2.1: iCloud sync improvements + ASO multilingual metadata

iCloud sync:
- Force viewContext.refreshAllObjects() on remote change notifications so
  data from other devices is picked up immediately without app restart
- Call refreshFromCloudKit() on foreground to merge any changes made while
  the device was inactive
- Wait up to 10s for initial CloudKit sync on launch before showing onboarding
  (shows "Checking iCloud..." during the wait)
- New OnboardingICloudCheckView: shown on fresh installs with iCloud available,
  lets user restore from iCloud before starting onboarding from scratch

Localization:
- Added de, fr, it, ja, pt-BR lproj folders
- New iCloud onboarding strings in en + es-ES (+ button literals)

ASO metadata (fastlane):
- Updated en-US: new subtitle, keywords, description (fixed "no cloud sync"
  claim), promotional text, release notes
- Added full metadata for es-ES, de-DE, fr-FR, it, ja, pt-BR (63 files total)
- All keyword fields validated ≤100 Unicode chars

Infrastructure:
- Gemfile + Gemfile.lock for fastlane
- Scripts/archive_and_upload_appstore.sh for CI/CD

Version: 1.2.1 (build 7)
