Add persistent upload progress indicator across all tabs

- Add progress broadcast from service to ViewModel with bytes and percentage
- Display global progress bar above tab content in MainScreen
- Show upload progress (MB uploaded/total, percentage) persistently
- Remove redundant in-tab progress indicators
- Progress stays visible when switching between Upload and Dumpstate tabs
- Matches cloud storage app UX (Google Drive, Dropbox)
