- LocalPhotoIndex: add count(filter:) so fast-path reconcile uses the
filtered asset count as phoneTotal instead of the unfiltered totalCount;
fixes the broken alreadySafe + needBackup == phoneTotal invariant
- BackupStatusService: fast-path uses count(filter:) instead of totalCount;
writeManifest falls back to NASManifestCache when NAS download fails so
accumulated history is never silently discarded on a flaky connection
- ConnectionStore: autoBackupEnabled defaults false; new autoBackupOnOpen
(default false) separates LAN-join auto-backup from app-open auto-backup
- AutoBackupCoordinator: onActive(lanTriggered:) tracks trigger source;
handleReconciliationComplete gates on autoBackupEnabled for LAN joins and
autoBackupOnOpen for app-open — prevents backup starting on every launch
- SettingsView: split auto-backup into two toggles with accurate descriptions
