The formatBytes function was used in the view but never defined, causing
a runtime error. This function was needed to display S3 file sizes in
human-readable format (e.g., "1.5 MB" instead of "1572864").
Added formatBytes() helper to bootstrap/helpers/shared.php:
- Converts bytes to human-readable format (B, KB, MB, GB, TB, PB)
- Uses base 1024 for proper binary conversion
- Configurable precision (defaults to 2 decimal places)
- Handles zero bytes case
