fix: use Base-10 sizes and mdls logical size to match macOS Finder

Browse Source 
- Switch bytes_to_human (shell) and humanizeBytes (Go) from Base-2
  (1024) to Base-10 (1000) to match Apple's storage calculation
  standard since Snow Leopard
- Add proper decimal rounding instead of truncation
- Use mdls kMDItemLogicalSize for .app bundles to avoid APFS clone
  file undercounting by du

Fixes #511
