Strictly limit logo width on homepage and guest pages

- Updated welcome.blade.php (homepage) to use 'w-32 h-auto' (128px width).
- Updated guest.blade.php (login/register) to use 'w-48 h-auto' (192px width).
- This addresses the user's feedback that the logo width was not constrained, causing it to appear too large.
