- Added phase constants (backupPhaseGlobals, backupPhaseDatabases, backupPhaseCompressing)
- Changed title from '[EXEC] Backup Execution' to '[EXEC] Cluster Backup'
- Made phase labels explicit with action verbs (Backing up Globals, Backing up Databases, Compressing Archive)
- Added realtime ETA tracking to backup phase 2 (databases) with phase2StartTime
- Moved duration display from top to bottom as 'Elapsed:' (consistent with restore)
- Standardized keys label to '[KEYS]' everywhere (was '[KEY]')
- Added timing fields: phase2StartTime, dbPhaseElapsed, dbAvgPerDB
- Created renderBackupDatabaseProgressBarWithTiming() with elapsed + ETA display
- Enhanced completion summary with archive info and throughput calculation
- Removed duplicate formatDuration() function (shared with restore_exec.go)
All 10 consistency improvements implemented (high/medium/low priority).
Backup and restore TUI views now provide unified professional UX.
