v1.1.0: Major refactoring and Android TV optimizations

## Screens

### home_screen.dart
- Removed unused imports (flutter/services)
- Removed unused _focusedIndex state variable
- Simplified responsive layout logic:
  - Removed _isMediumScreen, _gridCrossAxisCount getters
  - Removed _titleFontSize, _iconSize getters
  - Kept only _headerPadding for responsive padding
- Improved navigation with mounted checks
- Better MaterialPageRoute formatting
- Enhanced _downloadPlaylistAsJson method

## Services

### xtream_api.dart
- Added http.Client dependency injection for testability
- Implemented _countryExtractionCache for performance
- Added regex patterns for country code extraction:
  - _leadingCodeRegex for "AR - Channel" format
  - _bracketCodeRegex for "[AR] Channel" format
- Enhanced football channel detection patterns
- Improved error handling and messages
- Better formatted country mapping with regions

### iptv_provider.dart
- Better state management separation
- Optimized stream filtering for large lists
- Refactored country filtering methods
- Enhanced playlist download and caching logic
- Improved memory management

## Widgets

### countries_sidebar.dart
- Better responsive design for TV screens
- Enhanced FocusableActionDetector implementation
- Improved focus indicators for Android TV
- Smoother transitions between selections

### simple_countries_sidebar.dart
- Cleaner, more maintainable code structure
- Better keyboard/remote navigation support
- Improved visual feedback and styling

## Player

### player_screen.dart
- Better error handling for playback failures
- Enhanced responsive layout
- Improved Android TV control visibility
- Better buffer management and loading indicators

## Tests

### widget_test.dart
- Updated to match new widget signatures
- Improved test coverage for refactored components

## Technical Improvements

- Better separation of concerns across all layers
- Dependency injection patterns for testability
- Performance optimizations with caching
- Consistent code formatting and documentation
- Removed unused code and imports
- Enhanced Android TV support with FocusableActionDetector
