Implement Progress Indication for Long-Running Operations

[BhoomiAgrawal12]

Description

Long-running wipe operations (especially for large HDDs) currently show minimal progress feedback, leaving users uncertain about operation status and estimated completion time.

Current Behavior

• Basic progress bar exists but may not update smoothly
• No time estimate provided
• No indication of current phase (preparation, wiping, verification)
• Difficult to tell if operation is hung or progressing

Proposed Improvements

1. Enhanced Progress Display

   • Percentage complete
   • Estimated time remaining
   • Current operation phase
   • Data throughput (MB/s)
   • Bytes written / total bytes

2. Multi-Phase Progress

   • Show progress through multiple stages:
     • Device preparation
     • Security state check
     • Actual wiping
     • Verification (if enabled)
     • Certificate generation

3. Visual Improvements

   • Use ncurses progress bars effectively
   • Show spinning indicator for operations without percentage
   • Update at reasonable intervals (avoid flicker)

Technical Considerations

• Progress updates should not significantly impact wipe speed
• Need to query wipe progress from various commands (hdparm, dd, etc.)
• Handle cases where progress cannot be determined

Acceptance Criteria

• Progress percentage shown for all wipe types
• Time remaining estimate (can be rough)
• Current phase clearly indicated
• Progress updates smoothly without flickering
• Tested on operations taking >10 minutes

User Impact

High - Users frequently interrupt operations thinking they've hung when they're actually progressing normally.
