Fix community settings and admin panel layout issues

## Problems Fixed:
1. **Community settings grid layout** - Cards were too spread out horizontally
2. **Missing navigation elements** - No back link or breadcrumbs on community settings
3. **Admin panel grid layouts** - Stats and system info cards too wide on large screens
4. **Responsive layout issues** - Poor layout on different screen sizes

## Root Cause:
The CSS grid layouts were using `auto-fill` and `auto-fit` with minimum sizes that
caused elements to spread too wide on large screens, creating an awkward UI.

## Solutions Implemented:

### Community Settings Page:
- **Improved grid layout** - Better responsive grid with max 3 columns
- **Added back navigation** - "← Back to Settings" link for better UX
- **Responsive breakpoints** - Single column on mobile, max 3 on desktop
- **Better max-width** - Increased container width for better balance

### Admin Panel Base Template:
- **Fixed admin stats grid** - Limited to 4 columns max, responsive breakpoints
- **Fixed system info grid** - Limited to 3 columns max with proper responsive design
- **Added mobile support** - Single column layout on mobile devices
- **Improved spacing** - Better gap management and max-width constraints

### CSS Improvements:
- Mobile-first responsive design
- Proper breakpoints at 768px and 1200px
- Maximum column limits to prevent over-stretching
- Better visual balance on all screen sizes

The admin and community settings interfaces now have proper, responsive layouts\!
