Add pagination to library/songs and remove listening streaks

Library/Songs improvements:
- Added pagination with 50 songs per page
- Added Previous/Next navigation buttons
- Updated header to show current page range (e.g., 'Showing 1-50 of 247 songs')
- Track numbers now reflect global position across all pages
- Page resets to 1 when search/sort filters change
- Imported ChevronLeft and ChevronRight icons for navigation

Listening Streak removal:
- Removed CompactListeningStreak component from home page
- Removed ListeningStreakCard component from history page
- Removed listening streak imports from both pages
- Cleaned up empty comment sections

The songs page now handles large libraries more efficiently with pagination,
and the UI is cleaner without the listening streak cards.
