v1.1.2: Channel name formatting and Live TV search optimization

## New Features

### lib/utils/channel_name_formatter.dart (NEW)
- Created new utility class for formatting channel names
- Removes quality tokens (SD, HD, FHD, UHD, 4K, 8K, HDR, HEVC, H264, H265, FULLHD)
- Strips prefixes before pipe character (e.g., "AR | Channel" → "Channel")
- Removes leading dashes, colons, and other separators
- Implements caching mechanism (max 50,000 entries) for performance
- Normalizes tokens by removing non-alphanumeric characters

## UI/UX Improvements

### lib/screens/home_screen.dart
- **Live TV Memory Optimization**: Live streams list now persists in memory while app is running
  - Prevents unnecessary reloads when navigating back to Live TV
  - Improves performance and reduces API calls
- **Search Bar Visibility**: Hidden search bar for Live TV content type
  - Search only shown for Movies and Series
  - Cleaner UI for Live TV browsing
- **Channel Name Display**: Applied ChannelNameFormatter to channel cards
  - Removes quality indicators from displayed names
  - Better text styling with centered alignment
  - Increased font weight (w500 → w600)
  - Improved line height (1.15) for better readability
  - Text alignment changed to center
  - Better overflow handling with ellipsis

### lib/screens/player_screen.dart
- Code cleanup and optimization
- Removed unused imports/statements (9 lines removed)

## Technical Details

### Performance
- Channel name caching reduces string processing overhead
- Live TV list persistence reduces API calls
- Memory-efficient cache with automatic cleanup

### Code Quality
- Separation of concerns with new utility class
- Consistent formatting across channel names
- Better memory management for large channel lists
