Add alphabetical sorting for Android TV channel list

Alphabetical Sorting Features:
- ChannelRepository updated with alphabetical sorting
- ChannelAdapter optimized for sorted display
- Channel focus and selection improvements
- Added arrays.xml for channel categories and sorting
- Enhanced UI components for TV navigation

Code Changes:
- ChannelRepository: addSortChannels() method
- ChannelAdapter: optimized for alphabetical display
- AndroidManifest.xml: updated for sorting features
- item_channel.xml: improved focus states
- bg_channel_item_selector.xml: enhanced visual feedback

TV Navigation Improvements:
- Consistent alphabetical order (A-Z)
- Better focus management for D-Pad navigation
- Enhanced visual indicators for selected channels
- Improved readability on large screens
- Quick channel location with remote control

This improves the Android TV user experience by making channel discovery faster and more intuitive.
