Implemented proper time calculation matching the Brother app algorithm:
- 150ms per stitch + 3000ms startup time per color block
- Calculate total and elapsed time by summing across color blocks
- This fixes the "999 seconds" issue by calculating time accurately
Created timeCalculation utility with:
- convertStitchesToMinutes: Convert stitches to minutes using PP1 formula
- calculatePatternTime: Calculate total/elapsed time per color blocks
Updated ProgressMonitor to show:
- Total Time (calculated from all color blocks)
- Elapsed Time / Total Time (based on current stitch position)
