[PB-6100] feature/Handle offline and wifi option

[CandelR]

Handle WiFi only enforcement, and no connection backup pause

Summary

• src/store/slices/photos/index.ts:
  • added paused-no-wifi and paused-no-connection sync statuses.
  • runUploadThunk now checks network state before starting and listens for changes mid-upload via addNetworkStateListener, aborting immediately on WiFi or connection loss.
  • setNetworkConditionThunk aborts active uploads when switching to wifi-only on cellular.
  • photosBucket is now persisted to AsyncStorage.
  • runBackupCycleThunk reinitialises device folder if either deviceId or photosBucket is missing.
• GroupHeaderStatus.tsx: added GroupHeaderPausedNoWifi and GroupHeaderPausedNoConnection components shown in the timeline header when backup is paused due to network conditions.
• PhotosGroupHeader.tsx: extended GroupSyncStatus and renders the two new network-pause header states.
• photoTimelineGroups.ts: maps paused-no-wifi and paused-no-connection statuses to their GroupSyncStatus equivalents
