🔧 Fix installation success count when some locations fail

- Add successfulInstallations counter to track actual successful installations
- Show accurate count in summary messages instead of total attempted
- Differentiate between complete success and partial success:
  - 🎉 Green message when all locations successful
  - ⚠️ Yellow message when some locations failed
  - ❌ Red details showing number of failed installations
- Prevents misleading 'successfully installed in 4 location(s)!' when only 3 succeeded

Example outputs:
✅ All successful: '🎉 Setting installed in 3 location(s)!'
⚠️ Partial success: '⚠️ Setting installed in 3 of 4 location(s).'
                    '❌ 1 installation(s) failed due to permission or other errors.'

Fixes the case where enterprise settings fail due to permission denied
but user still sees success message for all locations.
