Add pagination to game launcher - 4 games per page

Browse Source 
- GameLauncher now displays only 4 games per page to keep menu in bounds
- Added page navigation with page indicator (Page X/Y)
- KEY0 navigates between pages and within page
- KEY1 selects the highlighted game
- Touch selection works on current page only
- Helper methods: get_total_pages(), get_page_start_index(), get_page_end_index()
- Updated both lib/ and emulator/ versions for consistency
