Release 1.3.1 (build 20): iCloud sync fix + sources search/filter

iCloud sync:
- Fix: deploy CloudKit schema to production so exports work
- Fix: PredictionCache marked syncable=NO (binary attr caused partial failures)
- Fix: forceExportToiCloud uses createdAt+1ms for guaranteed persistent history
- Fix: auto-deduplication on CloudKit import (processRemoteChanges)
- Add: NSPersistentHistoryTrackingKey always enabled regardless of CloudKit state
- Add: cloudKitForceReload notification so repositories re-fetch on remote changes

Sources UI:
- Add: horizontal category filter chips in SourceListView
- Add: search toggle button with animated TextField

Other:
- Add: ITSAppUsesNonExemptEncryption=NO in Info.plist (skip manual compliance)
- Add: fastlane submit lane with run_precheck_before_submit=false
- Update: release notes all locales for 1.3.1
- Update: fastlane API key via pass
