🎬 Add TopMeetupsScene component for Top Meetups (Scene 6)

Implements Scene 6 of the Portal presentation video, showcasing the top 5
most active Einundzwanzig meetups with animated rankings, sparkline charts,
and progress bars. Features 3D perspective entrance, staggered item animations,
and audio cues.
