feat: Add real system settings to admin dashboard

Backend:
- Added GET /admin/dashboard/settings endpoint
- Added POST /admin/dashboard/settings endpoint
- Returns settings from environment variables and defaults
- Includes General, Security, Notification, Email, Storage, and API settings
- Password fields are masked for security

Frontend:
- Removed deprecated MUI Grid import and components
- Replaced all Grid layouts with CSS Grid
- Connected settings page to real backend API
- Added loading state during initial fetch
- Added saving state with disabled button during save
- Proper error handling for fetch and save operations
- Settings now fetched from /admin/dashboard/settings on load
- Form spans 2 columns on desktop, single column on mobile

All 6 settings tabs now use real data from backend with proper responsive layout.
